We first check the dot product of "u" and "v" to determine if they are orthogonal ( dot product will be 0 ):

\(u\times v=(-3)\times(4)\div(9)\times(-12)\div(6)\times(-8)=-168\neq0\)

so that these vectors are NOT orthogonal. We nextdetermine if "u" and "v" arelinearly dependent:

\(\frac{(-3)}{(4)}=-\frac{3}{4}\)

\(\frac{(9)}{(-12)}=-\frac{-3}{4}\)

\(\frac{(6)}{(-8)}=-\frac{3}{4}\)

Hence, these vectors are linearly dependent and arethus parallel:

Vectors "u" and"v" Are PARALLEL
