Identifying solutions to a linear inequality in two variables

Question

For each ordered pair x,y, determine whether it is a solution to the inequality y<−2x-8

.

X Y

4 -19

2 -7

-5 2

-3 3

Are they a solution yes or No

Answer 1

Just plug each (x,y) value into the inequality and see if it's true. I'll do the first one, (4, -19):

y < -2x - 8

-19 < -2(4) - 8

-19 < -8 - 8

-19 < -16

which is true, -19 is less than -16. So yes, (4, -19) is a solution to the inequality.

You do the rest.
