# Chapter 9 - Section 9.4 - Variation and Problem Solving - Exercise Set: 6

The constant of variation is $33$. The direct variation equation is $y=33x$.

#### Work Step by Step

$y=kx$ $y=11; x=\frac{1}{3}$ $11=k(\frac{1}{3})$ $11\times3=k$ $33=k$ The constant of variation is $33$. The direct variation equation is $y=33x$.
