Answer
$y = \frac{7.7}{x}$ or $xy = 7.7$
Work Step by Step
Our equation for an inverse variation is $y = \frac{k}{x}$ or $xy = k$. We will use the second form of the equation to solve for k.
$2.2\times3.5 = k$
$ 7.7 = k$
$k = 7.7$
Therefore, our equation for the inverse variation is $y = \frac{7.7}{x}$ or $xy = 7.7$
