I suppose there is a mistake in typing in the last equation...  it is (z-3)/-6 ?? minus sign is missing ??

L1:    x/1 = y/2 = z/3  = m (let's say)
         x = m,  y = 2m ,  z = 3 m
         or  6 x = 3 y = 2 z

L2:   (x-1)/-2  = (y-2) /-4 = (x-3)/-6  = n
       x = 1 - 2n ,    y = 2 - 4n = 2 (1- 2n)      and  z = 3 - 6 n = 3 (1 - 2n)
         or    6 x  = 3 y = 2 z

Hence both represent the same straight line in 3 dimensional space.  They can represent two parallel straightlines in 3-d space.
