You can put this solution on YOUR website!
Since m is the slope, we can solve for m

y-y%5B1%5D=m%28x-x%5B1%5D%29 Start with the given equation

%28y-y%5B1%5D%29%2F%28x-x%5B1%5D%29=m Divide both sides by x-x%5B1%5D to isolate m


So the slope of y-y%5B1%5D=m%28x-x%5B1%5D%29 is m=%28y-y%5B1%5D%29%2F%28x-x%5B1%5D%29

So the answer is C)
