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--8%29%2F%28-4--4%29 Plug in y%5B2%5D=2, y%5B1%5D=-8, x%5B2%5D=-4, and x%5B1%5D=-4


m=%2810%29%2F%28-4--4%29 Subtract -8 from 2 to get 10


m=%2810%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.
