How do I find the intersection of these vector equations? I'm really confused. Thanks for the help.

Determine whether the lines L1 and L2 given by the vector equations are parallel, perpendicular, or neither. L1: r(t) = (4 + 4t)i + (2 + t)j L2: r(s) = (5 + 35)i + (4 12s)j If the lines are not parallel, find their point of intersection. (If the lines are parallel, enter PARALLEL.) (:x :Ex }
