Answer

Graph of $9x-2y=18$

Work Step by Step

The given linear equation, $9x-2y=18,$ can be graphed using the intercepts. That is, \begin{align*} \text{If }x=0: 9(0)-2y&=18 \\ -2y&=18 \\\\ \dfrac{-2y}{-2}&=\dfrac{18}{-2} \\\\ y&=-9 \\\\ \text{If }y=0: 9x-2(0)&=18 \\ 9x&=18 \\\\ \dfrac{9x}{9}&=\dfrac{18}{9} \\\\ x&=2 .\end{align*} Hence, the graph of $9x-2y=18$ is a line that passes through $(0,-9)$ and $(2,0)$.
