Note: is the first point . So this means that x%5B1%5D=-7 and y%5B1%5D=9.
Also, is the second point . So this means that x%5B2%5D=8 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=%283-9%29%2F%288--7%29 Plug in y%5B2%5D=3, y%5B1%5D=9, x%5B2%5D=8, and x%5B1%5D=-7


m=%28-6%29%2F%288--7%29 Subtract 9 from 3 to get -6


m=%28-6%29%2F%2815%29 Subtract -7 from 8 to get 15


m=-2%2F5 Reduce


So the slope of the line that goes through the points and is m=-2%2F5
