Consider the following scenario in 3D space:
A plane \(\Pi\) passes through the point A(1, 2, 3) and is parallel to the vectors \(u = \begin{pmatrix} 2 \\ -1 \\ 1 \end{pmatrix}\) and \(v = \begin{pmatrix} 1 \\ 1 \\ -2 \end{pmatrix}\).
A line L is given by its parametric equation: \(r = \begin{pmatrix} 4 \\ 0 \\ -1 \end{pmatrix} + t\begin{pmatrix} 1 \\ 2 \\ 3 \end{pmatrix}\), where \(t \in \mathbb{R}\).
Additionally, consider the point P(0, -2, 5).
Answer the following parts:
