Question

Which of the following ordered pairs is a solution to the inequality y -2x + 8?
(0, -4)

(5, -1)

(7, 0)

(9, 1)

Answer 1

What's between y and -2x?

Answer 2

greater than or equal to sign

Answer 3

checking (0,-4)

y >= -2x + 8

-4 >= -2(0) + 8 ... Plug in x = 0 and y = -4

-4 >= 0 + 8

-4 >= 8

since that's FALSE, this means that (0, -4) is NOT a solution

Answer 4

Do the same with the remaining points.
