here's the question:
determine wheter or not a single plane passes through the following lines:
L1: [x-1, y-2, z+3]= k[-4, -1, 8] L2: [x, y,z] = [-11, -1, 21]+L[8,2, -16]
if a plane exists, find its scalar equ'n
plz help..

The lines obviously are parallel (the direction vectors are scalar multiples), so there is a plane that contains them. There are lots of ways to find the equation of that plane, but if you have technology at hand, the fastest way is probably to solve a system created by the points you can get out of your lines:
A(1) + B(2) + C(-3) + D = 0 (L1, k=0)
A(-3) + B(1) + C(5) + D = 0 (L1, k=1)
A(-11) + B(-1) + C(21) + D = 0 (L2, L=0)
A(-3) + B(1) + C(5) + D = 0 (L2, L=1)
