Work Step by Step

Consider the given polar coordinate $\left( -3,0 \right)$ as $\left( r,\theta \right)$. Here, $\begin{align} & \theta =0 \\ & r<0 \\ \end{align}$ From above, it is clear that $\theta $ has been taken in the counter clockwise direction and $r<0$, so $r$ lies opposite to the terminal side. Hence, $\left( -3,0 \right)$ coordinate lies on the x-axis.
