The coordinate grid shows point $K$. The x-axis and y-axis intersect at the origin $(0,0)$. Coordinates are written as ordered pairs $(x,y)$.

Which ordered pair names point $K$?

$(2,4)$

$(5,2)$

$(2,5)$

$(4,2)$

Explanation

The coordinate plane uses two perpendicular number lines called the x-axis and y-axis. The origin is the point where they intersect, labeled (0,0). The first coordinate in an ordered pair represents the distance to move right along the x-axis from the origin. The second coordinate represents the distance to move up along the y-axis from the origin. A common misconception is miscounting the units on the grid, leading to wrong pairs. Ordered pairs name points by exact counts from the origin in each direction. Mastering this helps in plotting and recognizing points correctly on any grid.

A robot is programmed to move on a coordinate grid. It receives the command "GO TO (6, 4)" but there's an error in its movement system. Instead of moving to the correct location, it switches the x and y coordinates in its final position. From its incorrect position, what are the coordinates it needs to move to reach the intended destination?

From (4, 6) move to (-6, -4)

From (6, 4) move to (4, 6)

From (-6, -4) move to (6, 4)

From (4, 6) move to (6, 4)

Explanation

The robot was supposed to go to (6, 4) but switched coordinates, so it went to (4, 6) instead. To reach the intended destination (6, 4), it needs to move from its current incorrect position (4, 6) to (6, 4). Choice B reverses the problem. Choice C assumes the robot went to negative coordinates. Choice D suggests an incorrect destination.

Sarah is creating a coordinate plane map of her neighborhood. She places her house at the origin (0, 0). The school is 3 blocks east and 4 blocks north of her house. If each block represents 1 unit on the coordinate plane, and Sarah walks from school to a point that is the same distance east from the origin as the school, but 2 blocks south of her house, what are the coordinates of her final destination?

(4, -2) using the north distance incorrectly

(-3, -2) reflecting across both axes

(3, -2) representing the described location

(3, 2) forgetting the southern direction

Explanation

The school is at (3, 4) since it's 3 blocks east and 4 blocks north of the origin. Sarah's final destination is the same distance east as the school (3 units) but 2 blocks south of her house (which is at the origin), so the y-coordinate is -2. Therefore, the coordinates are (3, -2). Choice B uses 4 instead of 3 for the x-coordinate. Choice C uses +2 instead of -2. Choice D incorrectly makes the x-coordinate negative.

A coordinate grid shows the x-axis (horizontal) and y-axis (vertical) crossing at the origin $(0,0)$. Coordinates are written as ordered pairs $(x,y) and you move from the origin along the x-axis first, then along the y-axis. Which statement about the axes and ordered pairs is incorrect?

To locate a point, move from the origin along the x-axis, then along the y-axis.

The origin is where the x-axis and y-axis intersect.

In an ordered pair $(x,y)$, the y-coordinate is named first.

In an ordered pair $(x,y)$, the x-coordinate is named first.

Explanation

The coordinate plane uses two perpendicular number lines intersecting to form the basis of positioning. The origin at (0,0) is the crucial intersection, providing a starting reference. The first part of the ordered pair is the x-coordinate, guiding horizontal positioning. The second part is the y-coordinate, handling vertical positioning. A typical misconception is that negative coordinates aren't possible, but they extend the plane. Ordered pairs allow universal point location across the grid. This framework is key for mathematical modeling and real-world applications.

5

A student is learning the coordinate plane. On the coordinate grid, the x-axis and y-axis intersect at the origin $(0,0)$. Coordinates are written as ordered pairs $(x,y)$.

Which statement about the axes and ordered pairs is correct?

In $(x,y)$, $y$ tells how far right to move from the origin.

In $(x,y)$, the first number tells how far right to move from the origin.

In $(x,y)$, you should start counting from the point $(1,1)$.

In $(x,y)$, $x$ tells how far up to move from the origin.

Explanation

The coordinate plane uses two perpendicular number lines called the x-axis and y-axis. The origin is the point where they intersect, labeled (0,0). The first coordinate in an ordered pair represents the distance to move right along the x-axis from the origin. The second coordinate represents the distance to move up along the y-axis from the origin. A common misconception is that counting starts from (1,1) instead of (0,0). Ordered pairs ensure we start at the origin and move accordingly to find points. This foundational rule helps in understanding the entire coordinate system.

6

The coordinate grid shows a point $P$ in the first quadrant. The horizontal line is the x-axis and the vertical line is the y-axis. They intersect at the origin labeled $(0,0)$. Coordinates are written as ordered pairs $(x,y)$, meaning move right on the x-axis from the origin, then move up on the y-axis.

Which ordered pair names point $P$ on the grid?

$(4,2)$

$(2,5)$

$(2,4)$

$(5,2)$

Explanation

The coordinate plane uses two perpendicular number lines called the x-axis and y-axis. The origin is the point where they intersect, labeled (0,0). The first coordinate in an ordered pair represents the distance to move right along the x-axis from the origin. The second coordinate represents the distance to move up along the y-axis from the origin. A common misconception is confusing the order of the coordinates, such as thinking the first number means up and the second means right. Ordered pairs precisely locate points by specifying horizontal movement first, followed by vertical movement. This system allows us to name and find any point on the grid accurately.

7

The coordinate grid shows two points, $R$ and $S$, in the first quadrant. The origin is labeled $(0,0)$, and coordinates are written as ordered pairs $(x,y)$.

Which statement correctly compares the points based on their coordinates?

Point $R$ is farther right than point $S$.

Point $R$ is higher than point $S$.

Point $S$ is farther right than point $R$.

Point $S$ is higher than point $R$.

Explanation

The coordinate plane uses two perpendicular number lines called the x-axis and y-axis. The origin is the point where they intersect, labeled (0,0). The first coordinate in an ordered pair represents the distance to move right along the x-axis from the origin. The second coordinate represents the distance to move up along the y-axis from the origin. A common misconception is that a larger x-coordinate means a point is higher, but it actually means farther right. Ordered pairs help compare points by examining their x-values for horizontal position and y-values for vertical position. This allows us to describe relationships between points on the grid effectively.

8

The coordinate grid shows point $A$ in the first quadrant. The origin is labeled $(0,0)$, and coordinates are written as ordered pairs $(x,y)$.

Which ordered pair matches point $A$?

$(1,4)$

$(3,1)$

$(1,3)$

$(4,1)$

Explanation

The coordinate plane uses two perpendicular number lines called the x-axis and y-axis. The origin is the point where they intersect, labeled (0,0). The first coordinate in an ordered pair represents the distance to move right along the x-axis from the origin. The second coordinate represents the distance to move up along the y-axis from the origin. A common misconception is to misread the grid lines and assign the wrong values to x or y. Ordered pairs allow us to match points on the grid by counting units accurately in each direction. This method ensures we can identify points consistently in the first quadrant.

9

A game board uses a coordinate grid. The x-axis is horizontal and the y-axis is vertical. They meet at the origin $(0,0)$. Coordinates are written as ordered pairs $(x,y)$.

A student wants to place a token at $(5,1)$. Which set of directions is correct?

Start at $(0,0)$, move right 1, then up 5.

Start at $(0,0)$, move up 5, then right 1.

Start at $(0,0)$, move up 1, then right 5.

Start at $(0,0)$, move right 5, then up 1.

Explanation

The coordinate plane uses two perpendicular number lines called the x-axis and y-axis. The origin is the point where they intersect, labeled (0,0). The first coordinate in an ordered pair represents the distance to move right along the x-axis from the origin. The second coordinate represents the distance to move up along the y-axis from the origin. A common misconception is moving vertically before horizontally when following directions. Ordered pairs specify the sequence: horizontal first, then vertical, for accurate placement. This is essential for games and boards using coordinate systems.

10

On the coordinate grid, the x-axis is horizontal and the y-axis is vertical. They meet at the origin $(0,0)$. Coordinates are written as ordered pairs $(x,y) (x first, then y). What does the first number in the ordered pair $(x,y)$ tell you?

The total number of squares from the origin.

How far to move right from the origin on the x-axis.

How far to move up from the origin on the y-axis.

Which quadrant the point is in.

Explanation

The coordinate plane uses two perpendicular number lines, forming the x and y axes, to define positions. The origin is their intersection at $(0,0)$, acting as the zero point for measurements. The first number in the pair is the x-coordinate, telling the horizontal shift from the origin. The second number is the y-coordinate, indicating the vertical shift. A common misconception is that both numbers represent the same type of movement, but they are directional. Using ordered pairs, we can mark any spot on the grid with accuracy. This system supports various applications like graphing functions and analyzing data.
