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


m=%28-2-6%29%2F%283-1%29 Plug in y%5B2%5D=-2, y%5B1%5D=6, x%5B2%5D=3, x%5B1%5D=1, ,


m=%28-8%29%2F%283-1%29 Subtract 6 from -2 to get -8


m=%28-8%29%2F%282%29 Subtract 1 from 3 to get 2


m=-4 Reduce


So the slope of the line that goes through the points and is m=-4
