Use the distance and slope formulas to answer each question. Show your computations.

The four vertices of a quadrilateral are $P(0, 0)$ , $Q(4, 1)$ , $R(5, 5)$ , $S(1, 4)$ .
Compute the product of the slopes of sides $PQ$ and $QR$ . What does this product tell you?
Enter the numerical value of the product only.
