let L1 be the line throught (1,-6,2) with direction vector (1,2,1) and L2 be the line throught (0,4,1) with direction vector (2,1,2).Detrmine Whether trh lines are parallel,intersec or skew.if intersec,find the point of intersec
first step, come up with the equations for the lines.
L1: (x-1)/1 = (y+6)/2 = (x-2)/1
L2: x/2 = (y-4)/1 = (z-1)/2
See what you can do with that.
