1) (14 pts) Determine whether the lines L, and L, are parallel, intersecting, or skew. If they intersect, find the point of intersection. Show work! x =2+t x =3+s 4 : y =3-2t L2 : y = -4+3s z =1-3t z =2-7s a. Are they parallel? Show work b. Are they intersecting? Show work c. Are they skew? Conclusion based on parts a and b
