What would it be A. B. C. or D. http://i.imgur.com/6Su4PP1.png . . . .......
The method you owuld use to get to the answer is to plug in the vales for x and y (given by the points of each letter as (x,y), perform the operations and see if you have a true statement,
Testing with letter C (3,2) proves correct, since
2x + y = 8
2x3 + 2 = 8
6 + 2 = 8
8 = 8
The other letter choices wind up with statements of equality that are false.
