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


m=%28-5-2%29%2F%28-2--1%29 Plug in y%5B2%5D=-5, y%5B1%5D=2, x%5B2%5D=-2, and x%5B1%5D=-1


m=%28-7%29%2F%28-2--1%29 Subtract 2 from -5 to get -7


m=%28-7%29%2F%28-1%29 Subtract -1 from -2 to get -1


m=7 Reduce


So the slope of the line that goes through the points and is m=7
