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.
