Which list of ordered pairs represents solutions to x + y = 2 ? (-4, 6), (0, 2), (4, 2). (-4, 6), (0, 2), (4, -2). (-4, -6), (0, 2), (4, 2).

Answer 1

Each pair is (x,y) on the coordinate plane. So you are looking for the list where x+y = 2 (add the the two numbers in each ordered pair, is the answer 2?

Example (0,2) ==> x=0, y=2 and x+y = 0+2 = 2 (yes, this pair is a solution)

Check them all until you find one choice where all three pairs have x+y = 2.
