what do you think it is?

anonymous · Answer

i say a

anonymous · Answer

I say b, tho I have no idea if what I think direct variation is is what they say it is.

anonymous · Answer

Well I'm not too sure what it could be. I was pretty confused by it.

anonymous · Answer

Well from this website: http://www.freemathhelp.com/direct-variation.html It looks like they want it in y=kx form, which if divide the -3 over from the right, you get -5/3 which is why I said b

anonymous · Answer

True that, then I'm gonna go with B then. Thanks.
