Question

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

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

Answer 1

@Abhisar do you know how I could figure this out?

Answer 2

first step calculate the slopes of each vector

Answer 3

-2/6 or -1/3

and 24/8 or 3

Answer 4

do i just do that the same way as calculating the slope of 2 points?

Answer 5

yes y/x

Answer 6

oh i see. so what do i do after that?

Answer 7

well we know they are not paralell because they do not have the same slope

Answer 8

if you remember from algebra,to find the slope of a perpendicular line you take the negative reciprocal of the line

Answer 9

-1/3 is the negative reciprocal of 3

Answer 10

so they're orthogonal

Answer 11

ya id say so

Answer 12

thank you!!
