Answer:

A(0, 2), C(-1, 2), E(-4, -1)

Explanation:

It can be useful to graph the equations and plot the points. Only the points in the doubly-shaded area are solutions to the system of inequalities.

You can try the offered points and see which work.

y > 2x +1

A. 2 > 2·0 +1 . . . true

B. 3 > 2·1 +1 . . . . False

C. 2 > 2(-1) +1 . . . true

D. 1 > 2·1 +1 . . . . False

E. -1 > 2(-4) +1 . . . true

F. 0 > 2·0 +1 . . . . False

__

y < -2x +3

A. 2 < -2·0 +3 . . . true

C. 2 < -2(-1) +3 . . . true

E. -1 < -2(-4) +3 . . . true

Points A, C, E are in the solution set.
