Question

Which point lies in the solution set for the following system of inequalities?

2x + y > 8
x − y < 2

(1, 1)

(3, 4)

(5, −2)

(6, 1)

Answer 1

Checking (1,1)

2x + y > 8

2(1) + 1 > 8 ... Plug in x = 1 and y = 1

2 + 1 > 8

3 > 8

This is FALSE. So (1,1) is NOT in the solution set

Answer 2

Repeat this with the other answer choices until you find two true inequalities
