D

Answer 2

Answer 3

Well what you want to do is plug in the values. You are given a choice of answers (x, y). So plug the x value into the right hand side. Place the y value on the left side of the <

-6 < 2*3 - 5 which simplifies to -6 < 1

Answer 4

Since -6 < 1 it satisfies the inequality. Does my explanation make sense?

x=3 and y = -6 from the selection D (3, -6)
plug it into y < 2x - 5
