Which ordered pairs are a solution to the equation?

y = 3x

Select all that apply.

(-1,3)

(2,5)

(1,3)

(-2,-6)

(1,3) and (-2,-6) are the only ones that apply.

All you do is substitute all four of the coordinates back into the equation:

A. 3=3 (-1) 3=-3 So the first choice does not work.

B. 5=3 (2) 5=6 So the second choice doesn't work

C. 3=3 (1) 3=3 So the third choice works

D. - 6=3 (-2) - 6=-6 So the fourth choice works
