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

x1 y1 x2 y2
3 7 -5 1

slope m = (y2-y1)/(x2-x1)
( 1 - 7 )/( -5 - 3 )
( -6 / -8 )
m= 0.75 OR 3/4
