Right triangle $PQR$ is to be constructed in the $xy$ - plane so that the right angle is at $P$ and line $PR$ is parallel to the $x$-axis. The $x$ and $y$ coordinates of $P, Q,$ and $R$ are to be integers that satisfy the inequalities: $−4\leq x\leq 5$ and $6 \leq y \leq16.$ How many different triangles could be constructed with these properties? $110$ $1,100$ $9,900$ $10,000$
