Relationship between Point and Line

Question

Given the point P(−10,−8,9){P \left( - 10, - 8, 9 \right)} and the line
l:r=(−4−52)+λ(−2−12),  λ∈R,l: \mathbf{r} = \begin{pmatrix} - 4 \\ - 5 \\ 2 \end{pmatrix} + \lambda \begin{pmatrix} - 2 \\ - 1 \\ 2 \end{pmatrix}, \; \lambda \in \mathbb{R},
does P(−10,−8,9){P \left( - 10, - 8, 9 \right)} lie on l?{l?}
