Note: is the first point . So this means that x%5B1%5D=-2 and y%5B1%5D=3.
Also, is the second point . So this means that x%5B2%5D=5 and y%5B2%5D=-6.


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


m=%28-6-3%29%2F%285--2%29 Plug in y%5B2%5D=-6, y%5B1%5D=3, x%5B2%5D=5, and x%5B1%5D=-2


m=%28-9%29%2F%285--2%29 Subtract 3 from -6 to get -9


m=%28-9%29%2F%287%29 Subtract -2 from 5 to get 7


So the slope of the line that goes through the points and is m=-9%2F7
