To find the x-intercepts, plug
into the equation and solve for .
Don't forget that there are two solutions, both negative and positive!
Example Question #11 : How To Find X Or Y Intercept
A line with the exquation
passes through the point . What is the -intercept?
By plugging in the coordinate, we can figure out that
. The -Intercept is when , plugging in 0 for gives us .Example Question #11 : How To Find X Or Y Intercept
What are the
-intercept(s) of the following line:
We can factor
and set equal to zero to determine the -intercepts.satisfies this equation.
Therefore our
-intercepts are and .Example Question #11 : How To Find X Or Y Intercept
Which of the following lines does not intersect the line
?
Parallel lines never intersect, so you are looking for a line that has the same slope as the one given. The slope of the given line is –4, and the slope of the line in y = –4x + 5 is –4 as well. Since these two lines have equal slopes, they will run parallel and can never intersect.
Example Question #12 : How To Find X Or Y Intercept
Where does the line given by
intercept the -axis?
First, put in slope-intercept form.
.
To find the
-intercept, set and solve for .
Example Question #13 : How To Find X Or Y Intercept
Find the y-intercept of
.14
7
5
3
12
7
To find the y-intercept, set x equal to zero and solve for y.
This gives y = 3(0)2 + 2(0) +7 = 7.
Example Question #12 : How To Find X Or Y Intercept
The slope of a line is
. The line passes through . What is the x-intercept?
None of the available answers
The equation for a line is:
, or in this case
We can solve for
by plugging in the values given
Our line is now
Our x-intercept occurs when
, so plugging in and solving for :
