Question

(Medals!!!!!!!!!!!)

Determine whether the relationship is an inverse variation, a direct variation, or neither. Give 2 other ordered pairs that could continue the data set.

Answer 1

Each time it goes up +12.

Answer 2

@SolomonZelman So the answer is "Neither" because it has indirect and linear?

Answer 3

And are you sure, it's the correct answer? @SolomonZelman

Answer 4

Does it have the two ordered pairs? @SolomonZelman

Answer 5

Well it does have the coordinates,
4y=48x

SORRY, it's DIRECT.

Answer 6

Yes it's
y=12x

Answer 7

4y = 48 and y = 12x?

Answer 8

48=(12)4
60=(12)5
72=(12)6
84=(12)7

Answer 9

See?

Answer 10

So, it's direct and not neither?

Answer 11

No, just DIRECT.

Answer 12

Like he said, it's direct.
Use the direct variation formula: k = y/x

Feet = y
Inches = x

If you keep on plugging the number in, k would always be 12.
Therefore, it's direct. ^_^

Answer 13

Direct variation?

Answer 14

Yep!

Answer 15

But I don't get the ordered pairs thing.

Answer 16

Hmm. We know that k = 12
So: 12 = y/x
In other words, 12x = y

So pick any x, like 20.
12(20) = y
12 * 20 = ?

Answer 17

240? @GoldPhenoix

Answer 18

Yep. So you have one ordered pair: (20, 240)

Now choose any x and multiply it by 12.

Answer 19

Um, can you pick any number? @GoldPhenoix

Answer 20

Sure. Hmm. What about 100.
12(100) = ?

Answer 21

1200

Answer 22

Perfect. You found 2 ordered pairs:
(20, 240) and (100, 1200)

I hope this help! :)

Answer 23

@GoldPhenoix Are these pairs correct and it has bigger numbers.

Answer 24

An ordered pairs are any numbers that follow a rule.
It can be (1200000000, 14400000000)
Yes, that's also an ordered pair.

Answer 25

There's an infinite pairs of that particular question!!! :O

Answer 26

Okay, so "Direct Variation" + "20, 40 and 100, 1200"?

Answer 27

Direct Variation, yes. (20, 240) and ( 100, 1200)

Answer 28

Thank you so much @GoldPhenoix! (:

Answer 29

No problem! :)
