Vector Equation of a Line II

Question

Find the equation of the line that is parallel to

l_2: \mathbf{r} = \begin{pmatrix} 0 \\ 4 \\ 4 \end{pmatrix} + \mu \begin{pmatrix} 3 \\ - 5 \\ 4 \end{pmatrix}, \; \mu \in \mathbb{R}

and passes through the point

{P \left( 1, 3, 5 \right).}

{l: }

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