The answer would be 12.4 .
The line has equation
where 
is any real number. 
is the line containing all scalar multiples of the vector (-1, 4, -3); we add (4, -4, 8) to shift the line so that it passes through this point while remaining parallel to the the line.
To get the symmetric form, we have
Solving for in each equation gives the symmetric form,
The line has intercepts in the coordinate planes wherever either the 
, 
, or 
coordinate is 0.
