Determine Whether the Pairs of Lines Are Parallel, Intersect at a Single

Multiple Choice

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 are skew.
B) The lines intersect at a single point,
C) The lines are parallel, distinct lines.
D) The lines are the same line.
