    Why don't you try replacing x and y with the values of the ordered pairs and see which makes a true statement?

    Just see for second inequality... by putting values and check that it must not imply the first equality y=x-5

    \[y \le x-5\] \[2\le -5-2 \] \[2\le-7\] False Move on to the next point

    \[y \ge -x-4\] \[-2\ge -5-4\] \[-2\ge -9\] True. Since that ordered pair makes both sentences true, that must be the answer.
