Constant of variation =1/2=12

Explanation:

For a direct variation in xx and yy (with yy as the dependent variable),
the direct variation equation is
color(white)("XXXX")y=color(green)(c)*xXXXXy=cx where color(green)(c)c is the constant of variation.

-6y=-3x6y=3x
color(white)("XXXX")rArr y = color(green)(1/2)x XXXXy=12x (after dividing both sides by (-6)(6)
