I'll do the first one to get you started

Let's find the slope of the line passing through the points and

Note: is the first point . So this means that and .
Also, is the second point . So this means that and .

Start with the slope formula.

Plug in , , , and

Subtract from to get

Subtract from to get

Reduce

So the slope of the line that goes through the points and is

P(3,7);Q(6,16)
slope of a line m = y2-y1/ x2-x1 for points (x1,y1) & (x2,y2)
use the formula for the above points
16-7 / 6-3
=9/3
=3
and the other was P(5,17);Q(17,17)
17-17/ 17-5
=0
