Vectors - Perpendicular Projection and Reflection in a Line

The line equation \({l}:\mathbf{r}=\left( \begin{matrix}-2\\1\\3\end{matrix}\right)+\lambda \left( \begin{matrix}1\\-2\\1\end{matrix} \right)\). Find the position vector of the foot \(N\) of the perpendicular from \(A\left( \begin{matrix}0\\2\\-3\end{matrix} \right)\) . Hence find the position vector of the image of \(A\) in the line \(l\) .
