Example Question #3 : How To Find Slope
Find the slope of the line given the two points:
Write the formula to find the slope.
Either equation will work. Let's choose the latter. Substitute the points.
Example Question #6 : How To Find Slope
What is the slope of the line with the equation
To find the slope, put the equation in the form of .
Since , that is the value of the slope.
Example Question #11 : How To Find Slope
Consider the line of the equation . The line of a function
has the same slope as that of
. Which of the following could be the definition of
?
The definition of is written in slope-intercept form
, in which
, the coefficient of
, is the slope of its line.
, so the slope of its line is
.
We must select the choice whose line has this slope. The definition of in each choice is also written in slope-intercept form, so we select the alternative with
-coefficient 5; the only such alternative is
.
Example Question #2077 : Hspt Mathematics
What is the -intercept of the graph of the function
?
The -intercept of the graph of a function is the point at which it intersects the
-axis - that is, at which
. This point is
, so evaluate
:
The -intercept is
.
Example Question #2078 : Hspt Mathematics
Give the -intercept, if there is one, of the graph of the equation
The graph has no -intercept.
The graph has no -intercept.
The -intercept is the point at which the graph crosses the
-axis; at this point, the
-coordinate is 0, so substitute
for
in the equation:
However, since this expression has 0 in a denominator, it is of undefined value. This means that there is no value of paired with
-coordinate 0, and, subsequently, the graph of the equation has no
-intercept.
Example Question #2 : How To Find X Or Y Intercept
Give the -intercept, if there is one, of the graph of the equation
The graph has no -intercept.
The -intercept is the point at which the graph crosses the
-axis; at this point, the
-coordinate is 0, so substitute
for
in the equation:
The -intercept is
.
Example Question #4 : Use Similar Triangles To Show Equal Slopes: Ccss.Math.Content.8.Ee.B.6
Give the -intercept, if there is one, of the graph of the equation
.
The graph does not have a -intercept.
The -intercept is the point at which the graph crosses the
-axis; at this point, the
-coordinate is 0, so substitute
for
in the equation:
The -intercept is the point
.
Example Question #5 : Use Similar Triangles To Show Equal Slopes: Ccss.Math.Content.8.Ee.B.6
A line passes through and is perpendicular to the line of the equation
. Give the
-intercept of this line.
The line has no -intercept.
First, find the slope of the second line by solving for
as follows:
The equation is now in the slope-intercept form ; the slope of the second line is the
-coefficient
.
The first line, being perpendicular to the second, has as its slope the opposite of the reciprocal of , which is
.
Therefore, we are looking for a line through with slope
. Using point-slope form
with
,
the equation becomes
.
To find the -intercept, substitute 0 for
and solve for
:
The -intercept is the point
.
Example Question #6 : Use Similar Triangles To Show Equal Slopes: Ccss.Math.Content.8.Ee.B.6
A line passes through and is parallel to the line of the equation
. Give the
-intercept of this line.
The line has no -intercept.
First, find the slope of the second line by solving for
as follows:
The equation is now in the slope-intercept form ; the slope of the second line is the
-coefficient
.
The first line, being parallel to the second, has the same slope.
Therefore, we are looking for a line through with slope
. Using point-slope form
with
,
the equation becomes
.
To find the -intercept, substitute 0 for
and solve for
:
The -intercept is the point
.
Example Question #1 : How To Find X Or Y Intercept
Give the -intercept of the line with slope
that passes through point
.
The line has no -intercept.
By the point-slope formula, this line has the equation
where
By substitution, the equation becomes
To find the -intercept, substitute 0 for
and solve for
:
The -intercept is the point
.
