Example Question #36 : Graphing
What is the y-intercept of the line ?
The y-intercept is the point at which the line intersects the y-axis.
It does this at .
We plug in for in our equation, , to give us .
Anything multiplied by is , so .
Our coordinates for the y-intercept are .
Example Question #21 : Graphing
Graph the point .
The first number in the ordered pair indicates how far left or right the point resides from the origin. The second number in the ordered pair indicates how far up or down the point resides from the origin. Numbers that are positve are located on the right side and above the origin while negative numbers are located to the left of or below the origin. This point resides to 2 units to the right and 1 unit above the origin.
Example Question #2 : How To Graph A Point In Pre Algebra
Graph the point .
The first number in the ordered pair indicates how far left or right the point resides from the origin. The second number in the ordered pair indicates how far up or down the point resides from the origin. Numbers that are positve are located on the right side and above the origin while negative numbers are located to the left of or below the origin. This point is located 3 units to the left and 7 units above the origin.
Example Question #3 : How To Graph A Point In Pre Algebra
Graph the point
The first number in the ordered pair indicates how far left or right the point resides from the origin. The second number in the ordered pair indicates how far up or down the point resides from the origin. Numbers that are positve are located on the right side and above the origin while negative numbers are located to the left of or below the origin.This point is located 4 units to the right and 5 units below the origin.
Example Question #33 : Graphing
What is the slope of the line that contains the points
and
To find the slope of a line with two points you must properly plug the points into the slope equation for two points which is
We must then properly assign the points to the equation as and .
In this case we will make our and our .
Plugging the points into the equation yields
Perform the math to arrive at
The answer is .
Example Question #32 : Graphing
What is the slope of the line ?
In the standard form of a line the slope is represented by the variable .
In this case the line has a slope of .
The answer is .

y-intercept:
The equation of the line is written in slope-intercept form, , where is the slope and is the y-intercept. In this example, the y-intercept is a negative number.
Example Question #21 : Graphing Lines
What is the slope of the line that contains the points and ?
To find the slope of a line with two points we must properly plug the points into the slope equation:
We must then assign the variables and .
In this case we will plug in for and for .
Plugging the points into the equation yields .
Perform the math to arrive at .
The answer is.
