Answer by josmiceli(19441)   (Show Source):
You can put this solution on YOUR website! The staring point would be
Where m = slope and ( , ) is a
known point on the line
Now if you multiply both sides by  , you get
At this point, if you're given  and
(,) you can just plug those values in
and put the equation in the form  .
If nothing more is given, though, you can still put this
in the form
 answer
The 2 terms together  equal  ,
the y-intercept in
--------------------------------------
For an example, say  and  ,
