Determine whether the 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.r = (3, 1, 4) + t(-1, 6, -2); R = (-6, 55, -14) + t(5, -30, 10)

A. The lines intersect at a single point, .
B. The lines are parallel, distinct lines.
