Note: is the first point . So this means that x%5B1%5D=-5 and y%5B1%5D=-1.
Also, is the second point . So this means that x%5B2%5D=2 and y%5B2%5D=-3.


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


m=%28-3--1%29%2F%282--5%29 Plug in y%5B2%5D=-3, y%5B1%5D=-1, x%5B2%5D=2, and x%5B1%5D=-5


m=%28-2%29%2F%282--5%29 Subtract -1 from -3 to get -2


m=%28-2%29%2F%287%29 Subtract -5 from 2 to get 7


So the slope of the line that goes through the points and is m=-2%2F7
