okay, you would need to plug in each answer choice to see which one makes the equation false. (x,y) (5,6) (-15,12) (0,3) (-10,-3) so now you know which ones are x and which ones are y, choose one of the points and plug into the equation. if it comes out false, then that point you chose is your answer.
OpenStudy (anonymous):
is it A ? @CloverRacer
OpenStudy (cloverracer):
no because it makes the equation true
OpenStudy (anonymous):
it was B
OpenStudy (cloverracer):
yep. (:
