    This one will probably take the least effort to just take it logically by elimination. Look at x>-3. How many of your answers do not have an x value greater than -3? Those are gone. Look at y>-1, how many of the answers do not have a y coordinate greater than -1? Those are gone too. Finally, what coordinate has a y value less than equal to 4 minus double the x divided by three? That is your answer.

    First test: B is immediately eliminated. X is not greater than -3. Second test: A and E are eliminated. Y is not greater than -1.
