Question

Determine whether the vectors u and v are parallel, orthogonal, or neither.

u = <6, -2>, v = <2, 6>

A.) Neither
B.) Orthogonal
C.) Parallel

Answer 1

B.) Orthogonal

Explanation:

Two vectors u and v whose dot product is u·v=0 are said to be orthogonal

u = <6, -2>, v = <2, 6>

u·v = u1*v1 + u2*v2

6*2 + -2 * 6

=12 -12

=0
