Question

Help please!

Determine whether the vectors u and v are parallel, orthogonal, or neither. u = <1, -2>, v = <-4, 8>

Answer 1

To check whether they are parallel or not, take the ratio of corresponding components : \[\dfrac{1}{-4} \\~\\~\\~\\ \dfrac{-2}{8}\]

area they equal ?

Answer 2

no

Answer 3

Are you really sure ?

Answer 4

\[\large \dfrac{1}{-4}~~~\stackrel{?}{=}~~~\dfrac{-2}{8}\]

Answer 5

Its true sorry.

Answer 6

Yes so the given vectors are parallel

Answer 7

I didn't think it would be that simple...Thank you!

Answer 8

yw

Answer 9

a picture is worth a thousand words draw it it's a straight line
