Question

I really need help!
Determine whether the vectors u and v are parallel, orthogonal, or neither.
u = <7, 2>, v = <21, 6>

Answer 1

What is v / 3?

Answer 2

What?

Answer 3

Oh, and I know it's not neither. Someone told me that, and I got it wrong the first time.

Answer 4

You didn't answer the question. You are given u and v. What is v/3?

Show me. It is a vector divided by a constant (scalar). What is the result?

Answer 5

Uhmm..
Ohhh.. Well, geez. Why could no one else make it that simple? 7, 2. So they are parallel?

Answer 6

That's it!!! I presume you managed v/3 = <21,6>/3 = <7,2> = u?

Answer 7

Yes! Thank you! You're fantastic. :DDD God bless you!
