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.
