Question 173898: When using point-form in algebra what do you do? y-y1=m(x-x1)
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 ,

-----------------
Now just plugging in the data into , I get

OK
