Consider the lines given by the vector functions
$\vec{l_1}(t) = \langle 2, 1, 1 \rangle + t\langle 5, 1, 3 \rangle$
$\vec{l_2}(t) = \langle 14, 5, 9 \rangle + t\langle 1, 1, 1 \rangle$
Determine if these lines are the same, parallel, intersecting, or skew. If the lines intersect, given the point of
intersection and tell me if the intersection is also a collision. If it is one of the other three options, leave the
second box blank.
