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.
