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. 31 . r = 〈 1 , 3 , 2 〉 + 〈 6 , − 7 , 1 〉 ; R = 〈 10 , 6 , 14 〉 + s 〈 3 , 1 , 4 〉
