Answer
y=-1.44x
Work Step by Step
Since the general form of a direct variation is y=kx, lets substitute the value of x and y given to us into this equation:
6/5=-5/6k (Divide both sides by -5/6)
-1.44=k
Now lets plug this back into the standard form of a direct variation:
y=-1.44x
This is our equation for this situation that relates x and y.
