The vectors are .
The dot product of u and v is .
(Apply dot product: )
(Substitute )
(Simplify)
The dot product of u and v is is not equal to zero, so the vector u and v are not orthogonal.
The point form of vectors u and v are .
The slope of vector u is .
The slope of vector v is .
The slope of vector u and v are not equal, so the vector u and v are not parallel.
The solution is neither orthogonal nor parallel.
