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


m=%28-1%29%2F%284-4%29 Subtract 5 from 4 to get -1


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


Remember, you cannot divide by zero. So this means that the slope is undefined.
