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). If the lines intersect at a single point, determine the point of intersection. r=(2,53) +(7,-9,- 1) R=(10,1,19) +s(2, - 1,4) Select the correct choice and, if necessary, fill in the answer boxes to complete your choice. 51 34 || 34 The lines intersect at the single point W 17117 (Simplify your answers.) . The lines are skew. . The lines intersect at all points on the line r(t). . The lines are parallel. 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). If the lines intersect at a single point, determine the point of intersection. x=3,y=6-t,z=1+tandx=-1-4s,y=1+5s,z=8-5s Select the correct choice and, if necessary, fill in any answer boxes to complete your choice.
