Question

match Thanks!
y + 15 = x (A) (3, -10)
x + 3y = 28 (B) (3, -5)
y - 5x = -20 (C) (3, -12)
25 + y = 5x (D) (-2, 10)

Answer 1

you just need to plug in the coordinates of x and y into the equation. If they make sense, that will be your answer.

Answer 2

for example, in the first question, y is -10 and x is 3. your equation will become -10+15=3 (which would be incorrect, since -10+15=5, not 3.)

Answer 3
