Note: is the first point . So this means that x%5B1%5D=1 and y%5B1%5D=-3.
Also, is the second point . So this means that x%5B2%5D=4 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=%28-3--3%29%2F%284-1%29 Plug in y%5B2%5D=-3, y%5B1%5D=-3, x%5B2%5D=4, and x%5B1%5D=1


m=%280%29%2F%284-1%29 Subtract -3 from -3 to get 0


m=%280%29%2F%283%29 Subtract 1 from 4 to get 3


m=0 Reduce


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