<h3>Answer: B. (3,-2)</h3>
There are two ways to confirm this is the answer. The first is to note that (3,-2) is on the boundary, so it is part of the solution set. This only works if the boundary line is a solid line (as opposed to a dashed or dotted line).
The second way is to plug (x,y) = (3,-2) into the given inequality to find that
which is a true statement. So this confirms that (3,-2) is in the solution set of the inequality.
