What you can do is first reform to $\displaystyle y=...$.

You probably know a straight line is determined by two points, so you can choose for example $\displaystyle x=1$ and $\displaystyle x=2$, enter this given $\displaystyle x$-values in the equation to get the $\displaystyle y$-values and draw the line.
