Question 192365
slope is rise over the run or the change in y over the change in x
:
(5-(-7))/(-2-1)=12/-3=-4 or (-7-5)/(1-(-2))=-12/3=-4
:
direction is important if you start with the first y coordinate for the change in y then you must also start with the first x coordinate for the change in x
and if you start with the 2nd y coorinate for the change in y then you MUST start with the 2nd x coordinate for the change in x.
