Question

Find the x- and y- intercepts for each equations. What is the x- and y- intercepts?
y= -2x + 8

Answer 1

The x-intercept is the value of x when y=0.
Thus, x-intercept is obtained by solving:
0=-2x+8, or x=4

Similarly, the y-intercept can be obtained from
y=-2(0)+8, or y=8
So the intercepts are (4,0),(0,8).
The equation can also be written in the intercept form:
x/4 + y/8 = 1
