Note: is the first point . So this means that x%5B1%5D=5 and y%5B1%5D=-4.
Also, is the second point . So this means that x%5B2%5D=-20 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--4%29%2F%28-20-5%29 Plug in y%5B2%5D=-3, y%5B1%5D=-4, x%5B2%5D=-20, and x%5B1%5D=5


m=%281%29%2F%28-20-5%29 Subtract -4 from -3 to get 1


m=%281%29%2F%28-25%29 Subtract 5 from -20 to get -25


m=-1%2F25 Reduce


So the slope of the line that goes through the points and is m=-1%2F25
