Note: is the first point and is the second point .


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


m=%28-7-2%29%2F%28-3--1%29 Plug in y%5B2%5D=-7, y%5B1%5D=2, x%5B2%5D=-3, and x%5B1%5D=-1


m=%28-9%29%2F%28-3--1%29 Subtract 2 from -7 to get -9


m=%28-9%29%2F%28-2%29 Subtract -1 from -3 to get -2


m=9%2F2 Reduce


So the slope of the line that goes through the points and is m=9%2F2
