The slope is the change in y divided by the change in x, also called "rise over run".
.
The two points are (2,4) and (-1,-2).
.
Change in y is:
-2 -4 = -6
.
Change in x is:
-1 -2 = -3
.
Slope = -6/-3 = 2
.
Done.

Slope = [the change in the y-values] divided by [the change in the x-values] between the two points, or

m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29

Be sure not to mix up your x- and y-values for each point (lol)!
===
m=%28-2-4%29%2F%28-1-2%29
m=-6%2F-3
m=2

The slope of the line passing through (2,4) and -1,-2) is 2.
