Note: is the first point . So this means that x%5B1%5D=-3 and y%5B1%5D=56.
Also, is the second point . So this means that x%5B2%5D=-7 and y%5B2%5D=-65.


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


m=%28-65-56%29%2F%28-7--3%29 Plug in y%5B2%5D=-65, y%5B1%5D=56, x%5B2%5D=-7, and x%5B1%5D=-3


m=%28-121%29%2F%28-7--3%29 Subtract 56 from -65 to get -121


m=%28-121%29%2F%28-4%29 Subtract -3 from -7 to get -4


m=121%2F4 Reduce


So the slope of the line that goes through the points and is m=121%2F4
