Replace x and y in the equation with the x- and y-coordinates of each choice, respectively, and see which one makes the equation true.

anonymous · Answer

I believe the answer is C because when you replace the coordinates of the answer C. with the coordinates in the question you get the answer of -5. 
P.S may I please have another medal? XD
