The formula for this is:
%28y2-y1%29%2F%28x2-x1%29


So, plug in your values:
%282--3%29%2F%28-2--8%29


That gives you:
5%2F6


So, your slope is 5/6.

Let's denote the first point (-8,-3) as . In other words, and

Now let's denote the second point (-2,2) as . In other words, and



-------------------------



m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29 Start with the slope formula

m=%282--3%29%2F%28-2--8%29 Plug in y%5B2%5D=2,y%5B1%5D=-3,x%5B2%5D=-2,x%5B1%5D=-8


m=5%2F6 Subtract the terms in the numerator 2--3 to get 5. Subtract the terms in the denominator -2--8 to get 6

---------------------
Answer:

So the slope of the line through the points (-8,-3) and (-2,2) is m=5%2F6
