y2-y1
-------
x2-x1
That gives you slope. To remember that it's "rise over run."
(-5-8)/(-4+3)...which would be 13/1...so that's up 13 units and to the right 1.

A slope is the change in Y over the change in X. In other words, the incline or decline of a line.
In this case, the line suggested by these points has a slope of
(8+5), the change in Y
divided by
(-4+5), the change in X
13/1 = 13

Slope is the steepness of a line.
slope is the m in an equation, y=mx+b.
I'm a little rusty lol..
Sorry thats where I stop. I think you have to use slope intercept form

slope is the ratio between the change in y & the change in x.
the formula is
m=(y2=y1)/(x2-x1)=(8- (-5))/(-3-(-4))
m=13/1=13
