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


m=%287-8%29%2F%28-4-2%29 Plug in y%5B2%5D=7, y%5B1%5D=8, x%5B2%5D=-4, and x%5B1%5D=2


m=%28-1%29%2F%28-4-2%29 Subtract 8 from 7 to get -1


m=%28-1%29%2F%28-6%29 Subtract 2 from -4 to get -6


m=1%2F6 Reduce


So the slope of the line that goes through the points and is m=1%2F6
