(-1, 3) and perpendicular to y = -1/3x + 7.

y = 3x - 12

y = 3x + 6

y = 3x - 6

y = 3x

What do I do? Is there a formula?

 y = 3x

yes, perpendicular lines have negative reciprical slopes.
because the slope of the given line is -1/3
the perpendicular line will have a slope of 3.
now just find a line with a slope of 3 that passes through the given point 
(-1,3)

So as of right now I have Y=3x now I need to trial and error to find out what slope will get me to go through the point -1,3?

Never mind I think I got it, thanks @michaeljeff   :D
