Which ordered pair is a solution of the equation y=x-2? A (3.1)
B (1,3)
C (-1,3)
D (3,-1)

A

Step-by-step explanation:

y = x - 2

Well A should work. Let's try it.

y = 3 - 2

y = 1

So (3,1) is a solution

1,3

1 - 2 = -1. That's not the same as 3 so B does not work.

(-1,3)

y = -1 - 2

y = - 3  So this doesn't work either.

3,-1

y = 3 - 2

y = 1           just as we found for A. D is not an answer. The answer is A.
