Note: is the first point . So this means that x%5B1%5D=2 and y%5B1%5D=-4.
Also, is the second point . So this means that x%5B2%5D=-3 and y%5B2%5D=-4.


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


m=%28-4--4%29%2F%28-3-2%29 Plug in y%5B2%5D=-4, y%5B1%5D=-4, x%5B2%5D=-3, and x%5B1%5D=2


m=%280%29%2F%28-3-2%29 Subtract -4 from -4 to get 0


m=%280%29%2F%28-5%29 Subtract 2 from -3 to get -5


m=0 Reduce


So the slope of the line that goes through the points and is m=0
