Note: is the first point . So this means that x%5B1%5D=5 and y%5B1%5D=3.
Also, is the second point . So this means that x%5B2%5D=8 and y%5B2%5D=-4.


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


m=%28-4-3%29%2F%288-5%29 Plug in y%5B2%5D=-4, y%5B1%5D=3, x%5B2%5D=8, and x%5B1%5D=5


m=%28-7%29%2F%288-5%29 Subtract 3 from -4 to get -7


m=%28-7%29%2F%283%29 Subtract 5 from 8 to get 3


So the slope of the line that goes through the points and is m=-7%2F3
