Question 1197068: Find the x- and y-intercepts.
y = 2x − 8

x-intercept(x, y) = _________?
y-intercept(x, y) =__________?

You can put this solution on YOUR website!
y = 2x - 8
let x = 0 to get:
y = -8
that-s your y-intercept.
it's the value of y when x = 0
let y = 0 to get:
0 = 2x - 8
add 8 to both sides to get:
8 = 2x
divide both sides by 2 to get:
4 = x
that's the x-intercept.
it's the value of x when y = 0.
graph the equation and look for the value of x when y = 0 and the value of y when x = 0.
you will see that y = -8 when x = 0 at the coordinate point of (0,-8) and x = 4 when y = 0 at the coordinate point of (4,0).
