Right triangle PQR is to be constructed in the xy-plane so that the right angle is at P and \overline{PR} is parallel to the x-axis. The x- and y-coordinates of P, Q, and R are to be integers that satisfy the inequalities -4 \le x \le 5 and 6 \le y \le 16. How many different triangles with these properties could be constructed?
