Let $A$ be the point of intersection of the lines $3xy=1$ and $y=1$. Let $B$ be the point of reflection of the point $A$ with respect to the $y$axis. Then the equation of the straight line through $B$ that produces a right angled triangle $ABC$ with $\angle ABC=90^{\circ}$, and $C$ lies on the line $3xy=1$, is $3x3y=2$ $2x+3=0$ $3x+2=0$ $3y2=0$

GATE2015 ME3: GA9
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 xaxis. 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? $110$ $1,100$ $9,900$ $10,000$
