When solving a problem where you have to find a perpendicular line you must find the x and y intersepts for the perpendicular line.
you plug in the point given to you into either form
y= mx+b
slope intercept form
or
y-y=m(x-x)
point slope form

remember that in point-slope form the equation is:
ReplyDeletey-y sub 1=m(x-x sub 1)
*sorry I don't know how to make the "sub 1" on the computer!
Thank you so much callie! Sorry I forgot to put that in the post!
