Question

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

u = <7, 2>, v = <21, 6>

Answer 1

i now they're not orthogonal but how about parallel?

Answer 2

hint: if you are setting off from the origin, can you get to (21,6), which is where \( \vec v\) would take you in 1 step, but in smaller steps of \( \vec u\)?
