Note: is the first point . So this means that x%5B1%5D=-8 and y%5B1%5D=-4.
Also, is the second point . So this means that x%5B2%5D=2 and y%5B2%5D=-7.


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


m=%28-7--4%29%2F%282--8%29 Plug in y%5B2%5D=-7, y%5B1%5D=-4, x%5B2%5D=2, and x%5B1%5D=-8


m=%28-3%29%2F%282--8%29 Subtract -4 from -7 to get -3


m=%28-3%29%2F%2810%29 Subtract -8 from 2 to get 10


So the slope of the line that goes through the points and is m=-3%2F10
