Note: is the first point . So this means that x%5B1%5D=4 and y%5B1%5D=1.
Also, is the second point . So this means that x%5B2%5D=-4 and y%5B2%5D=1.


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


m=%281-1%29%2F%28-4-4%29 Plug in y%5B2%5D=1, y%5B1%5D=1, x%5B2%5D=-4, and x%5B1%5D=4


m=%280%29%2F%28-4-4%29 Subtract 1 from 1 to get 0


m=%280%29%2F%28-8%29 Subtract 4 from -4 to get -8


m=0 Reduce


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