Points $\displaystyle \mathrm{P}(-3,2), \mathrm{Q}(9,10)$ and $\displaystyle \mathrm{R}(\alpha, 4)$ lie on a circle C with PR as its diameter. The tangents to C at the points Q and R intersect at the point S . If S lies on the line $\displaystyle 2 x-k y=1$, then k is equal to
$\displaystyle \_\_\_\_$.
