Make $y$ the subject of the formula.

#### Explanation:

Write an equation which has an $x$-term, a $y$-term and a number term so that $y$ is the subject of the formula.

The process would be to isolate the $y$ term on the left and then to divide each term by the numerical coefficient of $y$

As an example:

$3 x \textcolor{b l u e}{+ 5 y} = 20$

$\textcolor{b l u e}{5 y} = - 3 x + 20$

$y = - \frac{3}{5} x - \frac{20}{5}$

$y = - \frac{3}{5} x - 4 \text{ } \leftarrow$ slope-intercept form
