Answer 1

Plug in your x and y value with the coordinate they give you. For example, for (-5,2) you have x = -5, y = 2.
Now plug in these two values in the inequalities:
\[2\le(-5)-5\]\[2\ge-(-5)-4\]which simplifies as\[2\le-10\]\[2\ge1\]

Clearly it is not true that \[2\le-10\], so this first point is not the answer (the inequalitis must be satisfied for BOTH inequalities). So, do the same thing for the other 3 coordinates!!
