original proportion | directions | equivalent proportion
\\(\frac{y}{9} = \frac{b}{1}\\) | switch the means. | \\(\square\\)

Explanation:

Step1: Identify means in proportion

In $\frac{y}{9}=\frac{b}{1}$, the means are $9$ and $b$.

Step2: Switch the means

Swap the positions of the two means to form the new proportion.
$\frac{y}{b}=\frac{9}{1}$

Answer:

$\boldsymbol{\frac{y}{b}=\frac{9}{1}}$
