Question

Which of these are the intercepts of the graph of y = 3x – 12?


A.

(4, 0), (0, -12)




B.
(12, 0), (0, 4)




C.
(3, 0), (0, 4)




D.
(4, 0), (0, 3)




E.
(-4, 0), (0, -12)

Answer 1

A

Answer 2

if you let y=0; you get your x-intercepts
0=3x-12
3x=12
x=4
if you let x=0; you get your y-intercepts
y=-12
