OpenStudy (anonymous):

@jordanloveangel

OpenStudy (bloomlocke367):

@IQ250 no direct answers please.

OpenStudy (ilovecake):

It is D. Like @IQ250 said

OpenStudy (bloomlocke367):

@jordanloveangel do you know what direct variation is?

OpenStudy (anonymous):

Direct variation means : Either \(y = kx\) or \(x = ky\)

OpenStudy (jordanloveangel):

can u help with few more

OpenStudy (welshfella):

direct variation is y = kx where k is a constant indirect is y = k / x

OpenStudy (anonymous):

@IQ250 you are not right, and don't be here for only medals..

OpenStudy (jordanloveangel):

k

OpenStudy (anonymous):

@jordanloveangel I need your interaction if you really want help here..

OpenStudy (welshfella):

its not D because it can be written as (1/9) x Here k = 1/9

OpenStudy (bloomlocke367):

http://www.mathwords.com/d/direct_variation.htm that should help

OpenStudy (anonymous):

B and C are totally same as : \(y=kx\)

OpenStudy (anonymous):

In D, multiply by \(9\) both the sides..

OpenStudy (anonymous):

It is not D @Ilovecake ..

OpenStudy (anonymous):

In D, you will get : \(9y=x\) and hence it is of form \(x = ky\), so you are left with only one option..

OpenStudy (welshfella):

tell us what you think the answer to first one is

OpenStudy (welshfella):

examples of direct variation are y = 10x , y = 0.1 x y = x/4

OpenStudy (welshfella):

indirect variation si something like y = 2 / x

OpenStudy (welshfella):

now you can't miss it!

OpenStudy (anonymous):

@welshfella he has closed the question and satisfied with D.. :P Don't show him right path if he himself does not want to walk on it..

OpenStudy (anonymous):

And I am just kidding.. Go ahead @welshfella I know you can make him understand what is right and what is not.. :)
