Question

If y = 6x − 3, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs? (Provide an explanation why if possible.)
A) {(0, 3), (1, −9), (2, −15)}
B) {(0, −3), (2, 15), (4, 21)}
C) {(0, −3), (2, 9), (4, 21)}
D) {(0, 3), (−2, 15), (4, 21)}

Answer 1

The answer would be C
{(0, −3), (2, 9), (4, 21)}

Answer 2

[c] because when you plug in the coordinates to "y" and "x" the statement will be true. Ex: -3=-3, 21=21, and 9=9
