Question 1010513: I got this test from my teacher and I can't figure out how to write the equation. it says write the equation of the direct variation that includes the point (-6,2). I don't get how to create the equation using those points. Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Well, direct variation looks like
y = kx
If you are given an x and a y, you can plug them in to find k...like this...
2 = k(-6)
k = -1/3
so that your equation becomes
y = (-1/3)x
