Question

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

u = <6, -2>, v = <8, 24>

Answer 1

Please help T-T i am pretty much hopeless on this topic.

Answer 2

use the dot product \[\vec u • \vec v = |\vec u||\vec v|\cos \theta = u_xv_x + u_yv_y\]

theta is the angle between the vectors.
