Question

Which of the following ordered pairs is a solution to the inequality y less than or greater to -2x + 8

Answer 1

(0, -4)

(5, -1)

(7, 0)

(9, 1)

Answer 2

do you mean less then or equal ?

Answer 3

if so, lets sub some points in and see which one satisfies the inequality.

(0,-4) x = 0 and y = -4
y <= -2x + 8
-4 <= -2(0) + 8
-4 <= 8 (correct)
This is correct. I was gonna do one as an example, but the first one happens to be the answer.

Let me check the second one...
(5,-1) x = 5 and y = -1
y <= -2x + 8
-1 <= -2(5) + 8
-1 <= -10 + 8
-1 <= -2 (false) -1 is greater then 2.

anyways, do you understand how to do it now ? Just sub in your points and see which one is correct.
