y > x + 2

(-2, -5)

Answer 2

Please help? :S

Answer 3

The most straightforward way to go about this would be substituting each point in to the system and checking if it gives a correct result in BOTH inequalities.

Ex) (2, -5):
-5 > -3(2) + 3
-5 > -6 + 3
-5 > -3 not true!
So, (2, -5) is not in the solution set.
We test the other three points in the same way.
