Yes, the equation does represent a direct variation. Constant of Variation: 0.5
Work Step by Step
Our equation given is: 0.7x-1.4y=0 First lets solve for y: 0.7x-1.4y=0. (Subtract 0.7x from both sides) -1.4y=-0.7x (Divide both sides by -1.4) y=0.5x The question asks for the constant of variation which is the coefficient of the x-term. In our case it is 0.5 so that is the constant of variation.
