How do you find the x and y-intercept of y=2x - 4

Answer 1

In ANY equation to find the x-intercept, let y = 0
to find the y-intercept, let the x = 0

furthermore, since y = 2x - 4 is in the form y = mx + b
you should recognize -4 as the y-intercept without any work.

Answer 2

or, use the intercept form for the line
y=2x - 4
2x - y = 4
x/2 - y/4 = 1
the intercepts are 2 and 4
