You can put this solution on YOUR website! The slope, 'm', is defined as the rise divided by the run.
The rise is the change in 'y'.
The run is the change in 'x'.
The change in 'y' is defined as y2 - y1.
The change in 'x' is defined as x2 - x1.
.
We have two points:
(-3, 5) = (x1, y1)
(6, -1) = (x2, y2)
.
y2 - y1 = -1 -5 = -6
x2 - x1 = 6 - (-3) = 9
.
m = -6/9 = -2/3
.
