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


m=%28-8-5%29%2F%285--11%29 Plug in y%5B2%5D=-8, y%5B1%5D=5, x%5B2%5D=5, x%5B1%5D=-11, ,


m=%28-13%29%2F%285--11%29 Subtract 5 from -8 to get -13


m=%28-13%29%2F%2816%29 Subtract -11 from 5 to get 16


So the slope of the line that goes through the points and is m=-13%2F16
