Chapter B, Problem 60E

$\left(a\right)$

To determine

The equation of the sides of the triangle with vertices $P\left(1,0\right),Q\left(3,4\right)\text{ and }R\left(-1,6\right)$ .

$\left(b\right)$

To determine

The equations of the medians of the triangle with vertices $P\left(1,0\right),Q\left(3,4\right)\text{ and }R\left(-1,6\right)$ and also find the point of intersection of the medians.
