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


m=%28-12%29%2F%28-5--2%29 Subtract 5 from -7 to get -12


m=%28-12%29%2F%28-3%29 Subtract -2 from -5 to get -3


m=4 Reduce


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