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

The best thing to do in here is to substitute each given points from the choices in the given equation.

Answer 2

how would I do that?

Answer 3

0=3(4)-12
0=12-12
0=0
like that?

Answer 4

For example in letter A.
First we have (4,0) --> then 0 = 3(4)-12 --> and that is true
another one. (0, -12) --> then -12 = 3(0) - 12 --> true also
therefore, A is the answer.
