Question

Which of the following are the x and y intercepts of the equation 4x - 2y = 8?

(3, 0) and (0, 4)


(2, 0) and (0, 4)


(-2, 0) and (0, -4)


(2, 0) and (0, -4)

Answer 1

If x=0 you get the y intercept
If y=0 you get the x intercept

Answer 2

so replace x in the equation by 0 then you can calculate y
and vice versa
