Question 1302f

Vectors II: Lines and Planes
Relationship between Lines

Question

The lines l1{l_1} and l2{l_2} are given by
l1:r=(−22−3)+λ(−3−31),  λ∈R,l2:r=(−52−1)+μ(5−53),  μ∈R.\begin{align*} &l_1: \mathbf{r} = \begin{pmatrix} - 2 \\ 2 \\ - 3 \end{pmatrix} + \lambda \begin{pmatrix} - 3 \\ - 3 \\ 1 \end{pmatrix}, \; \lambda \in \mathbb{R}, \\ &l_2: \mathbf{r} = \begin{pmatrix} - 5 \\ 2 \\ - 1 \end{pmatrix} + \mu \begin{pmatrix} 5 \\ - 5 \\ 3 \end{pmatrix}, \; \mu \in \mathbb{R}. \end{align*}
What is the relationship between the two lines?
