_____ Coordinate A: -5 = -4(1) - 1 -5 = -4 - 1 -5 = - 5 --- True _________ Coordinate B: 15 = -4(4) - 1 15 = -16 - 1 15 = - 17 ---False ________________ Coordinate C: -7 = -4(2) - 1 -7 = -8 - 1 -7 = -9 ---False ____________ Coordinate D: 1 = -4(-5) - 1 1 = 20 - 1 1 = 19 --- False

After plugging the points in the equation to test if they're true we see that Coordinate A is the answer.

first try plugging in the x values so 1,4,2, and -5. I only did 2 because right away it was proven that A) (1, -5) was right
