Note: is the first point . So this means that x%5B1%5D=-19 and y%5B1%5D=-7.
Also, is the second point . So this means that x%5B2%5D=-20 and y%5B2%5D=-17.


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


m=%28-17--7%29%2F%28-20--19%29 Plug in y%5B2%5D=-17, y%5B1%5D=-7, x%5B2%5D=-20, and x%5B1%5D=-19


m=%28-10%29%2F%28-20--19%29 Subtract -7 from -17 to get -10


m=%28-10%29%2F%28-1%29 Subtract -19 from -20 to get -1


m=10 Reduce


So the slope of the line that goes through the points and is m=10
