Yes, when finding the X-intercept, you make y=0.

So:

x - 2y = 4

x - 2(0) = 4

(2 x 0 = 0)

So then,:

x = 4

Put the point (4,0) on your graph, and that is the x-intercept. Trust me! I am in Algebra II and we just went over this. If you ever need help you can talk to me too!

(PS: To find the Y-intercept, do the same, except make X = 0.)

I love math.
