Note: is the first point and is the second point .


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


m=%282-2%29%2F%282--4%29 Plug in y%5B2%5D=2, y%5B1%5D=2, x%5B2%5D=2, and x%5B1%5D=-4


m=%280%29%2F%282--4%29 Subtract 2 from 2 to get 0


m=%280%29%2F%286%29 Subtract -4 from 2 to get 6


m=0 Reduce


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