Example Question #933 : Gmat Quantitative Reasoning
What is the -intercept of a line that includes points and ?
The slope of the line is
Use the point slope form to find the equation of the line.
Now substitute and solve for .
The -intercept is
Example Question #941 : Gmat Quantitative Reasoning
Give the area of the region on the coordinate plane bounded by the -axis, the -axis, and the graph of the equation .
This can best be solved using a diagram and noting the intercepts of the line of the equation , which are calculated by substituting 0 for and separately and solving for the other variable.
-intercept:
-intercept:
Now, we can make and examine the diagram below - the red line is the graph of the equation :
The pink triangle is the one whose area we want; it is a right triangle whose legs, which can serve as base and height, are of length . We can compute its area:
Example Question #1 : X And Y Intercept
What is the -intercept of
To solve for the -intercept, you have to set to zero and solve for :
Example Question #1 : X And Y Intercept
What is -intercept for
To solve for the -intercept, you have to set to zero and solve for :
Example Question #6 : X And Y Intercept
A line with slope includes point . What is the -intercept of this line in terms of ?
For some real number , the -intercept of the line will be some point . We can set up the slope equation and solve for as follows:
Example Question #3 : Calculating X Or Y Intercept
Give the -intercept(s) of the graph of the equation
The graph has no -intercept.
Substitute 0 for :
The -intercept is
Example Question #8 : X And Y Intercept
Give the -intercept(s) of the graph of the equation
Set
Using the -method, we look to split the middle term of the quadratic expression into two terms. We are looking for two integers whose sum is and whose product is ; these numbers are .
Set each linear binomial to 0 and solve:
or
There are two -intercepts -
Example Question #942 : Problem Solving Questions
A line includes and . Give its -intercept.
The line has no -intercept.
The line has no -intercept.
The two points have the same coordinate, which is 5; the line is therefore vertical. This makes the line parallel to the -axis, meaning that it does not intersect it. Therefore, the line has no -intercept.
