Consolidate - POINT SLOPE FORMULA is the SLOPE EQUATION

Did you ever realize that the SLOPE EQUATION is the SAME as the POINT SLOPE FORMULA???? WHAT?!?! Check it out:

POINT SLOPE FORMULA is (y-y1)=m(x-x1)

SLOPE EQUATION IS m = (y-y1)/(x-x1)

Can you see where I'm going with this?
-Take the first equation
-Divide both sides by (x-x1)
-The result is the second equation!!!

So now you've shortened your "list of equations to learn" without really doing anything ;)
