Equation of a Plane from the Normal Vector

Question

The plane

{p}

is given by

p: \mathbf{r} \cdot \begin{pmatrix} 1 \\ - 1 \\ - 5 \end{pmatrix} = - 15,

Find the equation of the line

{l}

that is perpendicular to

{p}

and contains the point

{A \left( - 1, 2, 2 \right).}

{l: }

{\mathbf{r}=\mathbf{a}+\lambda\mathbf{d}, \; \lambda \in \mathbb{R}.}

{\mathbf{a}=}

{\Biggl(}

{\Biggr), \quad}

{\mathbf{d}=}
