Answer
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.
