Question

The solutions to the inequality y<2x - 4 are shaded on the

graph. Which point is a solution?
(-1,1)
(1,-1)
(3,2)
(2,3)

Answer 1

None

Explanation:

y<2x - 4

Substitute points to determine if they are a solution

(-1,1)

1<2(-1) - 4

1 < -2-4

1 < -6 False not a solution

(1,-1)

-1<2(1) - 4

-1 < 2-4

-1 < -2 False not a solution

(3,2)

2<2(3) - 4

2 < 6-4

2 < 2 False not a solution

(2,3)

3<2(2) - 4

3 < 4-4

3 < 0 False not a solution
