Determine whether the following pair of lines is parallel, intersects at a single point, or is skew. If the lines are parallel, determine whether they are the same line (and thus intersect at all points).
lines intersect at a single point, determine the point of intersection.
r= (1,2,3) +t(4,-6,2)
R= (21,6,19) + s (5,1,4)
Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice.
OA. The lines intersect at the single point
(Simplify your answers.)
B. The lines are parallel.
OC. The lines are skew.
D. The lines intersect at all points on the line r(t).
