To complete each ordered pair, you would have to substitute the 1 and 2 in for y. Let's start with the 2 first. X-2 (2) = 7, x-4=7. Add 4 on each side. X=11. First ordered pair is (11,2). Now do the 1. X-2 (1) = 7, x-2=7. Add 2 on both sides. Second ordered pair is (9,1). Answers are (11,2) and (9,1)
