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=%284-4%29%2F%28-7-9%29 Plug in y%5B2%5D=4, y%5B1%5D=4, x%5B2%5D=-7, and x%5B1%5D=9


m=%280%29%2F%28-7-9%29 Subtract 4 from 4 to get 0


m=%280%29%2F%28-16%29 Subtract 9 from -7 to get -16


m=0 Reduce


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