Question

1. Determine if the following equations represent the same line
L1=(0,-2,3) + t(-1,1,2)
L2=(-1,1,1)+ v(-2,2,-4)
Supposed to be square bracklets.

Answer 1

The lines aren't even parallel, ....
(-2,2,-4) is not a multiple of (-1,1,2) , so there is no need to go further.

They are not the same line
