Answer:
parallel
Step-by-step explanation:
u = <-9,9,3>
v = <12,-12,-4>
test if the given vectors are orthogonal ( dot product = 0 )
we have to find the dot product of the vectors to determine is it will be = 0
u*v = (-9)*(12) + (9)*(-12) + (3)*(-4) = -108 -108 -12= -228 ≠ 0
hence the given vectors is not orthogonal
next check if the vectors are linearly dependent
(-9/12 ) = - 3/4
(9/-12) = - 3/4
( 3/-4 ) = - 3/4
since they are linearly dependent then they are parallel
