(MEDALS!!!!!!!!) Can someone please answer this question. Tell whether the relationship is an inverse variation, a direct variation, or neither.

OpenStudy (beccaboo333):

what do you think?

OpenStudy (beccaboo333):

that will help you, same with further times.

OpenStudy (anonymous):

@beccaboo333 It doesn't help me at all. I just need the answer so I can understand because it does.

OpenStudy (beccaboo333):

im not giving you the direct answer. you have the definitions right there to help you. @wolfe8 do you agree?

OpenStudy (anonymous):

Okay, I got my answer. Um, it's direct variation. Am I correct?

OpenStudy (wolfe8):

Can you tell me why you say it is direct?

OpenStudy (anonymous):

Because it increases the numbers and then decreases.

OpenStudy (wolfe8):

What I see is when x decreases, y increases

OpenStudy (anonymous):

Yeah.

OpenStudy (anonymous):

@wolfe8 So, am I correct?

OpenStudy (wolfe8):

How is it then direct?

OpenStudy (anonymous):

@wolfe8 Increases and decreases.

OpenStudy (wolfe8):

Don't you think they are going opposite directions then?

OpenStudy (anonymous):

Um, yes. Am I correct now?

OpenStudy (anonymous):

I mean, no.

OpenStudy (wolfe8):

If you read the link Becca gave you, you can answer it right away.

OpenStudy (anonymous):

I already read it.

OpenStudy (wolfe8):

They even show you a very similar example. One goes up, one goes down.

OpenStudy (anonymous):

Yeah, I know. Am I correct?

OpenStudy (wolfe8):

What is your answer?

OpenStudy (anonymous):

Inverse variation.

OpenStudy (wolfe8):

Yes

OpenStudy (anonymous):

So, I'm correct?

OpenStudy (wolfe8):

Yes

OpenStudy (anonymous):

Finally! Thank you, though.

OpenStudy (anonymous):

Wait, you sure this is correct?

OpenStudy (wolfe8):

You said direct earlier

OpenStudy (anonymous):

I know, I didn't read it correctly.

OpenStudy (wolfe8):

From what I know, it's inverse

OpenStudy (anonymous):

So you are sure?
