m = y2-y1/x2-x1
That's the correct definition, right? There's no y1-y2 version is there? Or does it not make a difference?  |
There are equivalent because with the first equation say you get -3/1 after the calculation. with the second one using the same numbers you would get 3/-1 which are equivalent.
