Question

Does (-1, 5) make the inequality y < 3x + 8 true?

Answer 1

Answer:

(–1, 5) does NOT make y < 3x + 8 true.

Step-by-step explanation:

First, let's substitute the values into the inequality. It's the one way to see if the point (–1, 5) is in the range of y < 3x + 8

5 ≟ 3(–1) + 8

5 ≟ 8 – 3

5 = 5 ✘

This means (–1, 5) does NOT make the inequality y < 3x + 8 true.

Answer 2

Answer:

No

Step-by-step explanation:

as X=-1. and y=5

according to this y<3x+8

which means 5< 3*-1 +8

5<-3+8

5<5

which is not true.. as 5=5
