Question

Which of the following ordered pairs is not a solution to the inequality y < -x + 6?

(-3, 0)

(-1, 0)

(4, 3)

(3, -2)

Answer 1

Checking choice A

y < -x + 6

0 < -(-3) + 6 ... plug in x = -3 and y = 0

0 < 3 + 6

0 < 9

This is true, so (-3,0) is a solution. So we can rule out choice A

Answer 2

Do the same for the rest until you find a false inequality
