Question

does this graph show a direct variation?

Answer 1

As long as it

a) goes through the origin (0,0)
AND
b) is a straight line

then it's a direct variation graph

Answer 2

all direct variation equations are in the form `y = k*x` (k is some fixed number)

`y = 2x` is in the form `y = k*x` where in this case `k = 2`

Answer 3

Oh ok @jim_thompson5910 would you mind checking a few more equation s to

Answer 4

*equations to see is f they are diDirect Variation

Answer 5

sure

Answer 6

ok thank you!

Answer 7

y = (3/4)x
I'm pretty sure this is one

Answer 8

@jim_thompson5910

Answer 9

yes k = 3/4 in this case. Hopefully you can see how

Answer 10

Ok thats what I thought it was

Answer 11

y = -1
This one isn't right?

Answer 12

nope because it's not in the form y = k*x

Answer 13

y = (5/2)x
And this one is?

Answer 14

what is k equal to here?

Answer 15

5/2

Answer 16

yep, you got the hang of this

Answer 17

ok Thank you!!! you really helped me!!

Answer 18

you're welcome
