\begin{align*} \text{$y$ does NOT vary directly with $x$} \end{align*}

Work Step by Step

Using the properties of equality, the given equation, $ y+\dfrac{3}{4}x=12 ,$ is equivalent to \begin{align*} y&=-\dfrac{3}{4}x+12 \end{align*} Since the equation above takes the form of $y=kx$ or the direct variation model where $k$ is the constant of variation, then \begin{align*} \text{$y$ does NOT vary directly with $x$} .\end{align*}
