Example Question #75 : Algebra I
What is the x-intercept of the following equation?
0
5
2
-5
10
5
We want to find the x-intercept, which is the point at which the graph crosses the x-axis. Every point on the x-axis has a y-value of 0. Thus, to find the x-intercept we just need to plug 0 in for y.
Thus, .
Dividing both sides by , we get .
Example Question #76 : Algebra I
What is the y-intercept of the following curve?
The y-intercept of a curve is the value of that curve when the x-coordinate is . Thus, we plug in to our equation, yielding .
