Parallel, Intersecting, or skew lines Determine whether the following pairs of lines are parallel, intersect at a single point, or are skew. If the lines are parallel, determine whether they are the same line (and thus intersect at all points). If the lines intersect at a single point, determine the point of intersection. 35 . x = 1 + 2 t , y = 7 ‒ 3 t, z = 6 + t and x = ‒9 + 6 t , y = 22 ‒ 9 t , z = 1 + 3 t

Solution Summary: The author explains that the lines are parallel and intersect at all points. They are skew lines if they are neither parallel nor intersecting.
