Given lines in parametric form
line 

direction vector of
Line 
direction vector of
therefore

thus lines are parallel.
(ii)distance between two lines is
is given by
=s
=3s

where
=3
=-2
=-3
=-9
=6
=9
distance(d)=0 units since value of the matrix

is zero
The problem is discrete, because the cost of movies cannot be below zero, and neither can the number of movies purchased
LM = LN
3x - 2 = 2x + 1
x = 3
LM = LN = 7
MN = 5x - 2 = 13
