Note: is the first point . So this means that x%5B1%5D=6 and y%5B1%5D=-7.
Also, is the second point . So this means that x%5B2%5D=9 and y%5B2%5D=-9.


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


m=%28-9--7%29%2F%289-6%29 Plug in y%5B2%5D=-9, y%5B1%5D=-7, x%5B2%5D=9, and x%5B1%5D=6


m=%28-2%29%2F%289-6%29 Subtract -7 from -9 to get -2


m=%28-2%29%2F%283%29 Subtract 6 from 9 to get 3


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