Question

Which ordered pairs from the replacement set are solutions to the equation?
y = -2x + 9 ; Replacement Set {((-1, 11), (0, 8), (1, 7), (2, 5)} can you help me work my way to the answer

Answer 1

plug in x and y and if they make the equation true then theyre solutions

first one:

11=-2(-1)+9
11=2+9
11=11

thats true so first one is a solution, do it with the rest

Answer 2

thank you
