Answer 1

Answer 2

Hey broski c:
Hmm, so th x values close to 0 produce large y's.
The y's get smaller as x increases in either direction.
We can describe this as an inverse relationship.

\(\Large\rm y=\dfrac{k}{x}\)

Answer 3

We need to use the information they gave us to find our k value.

Answer 4

Let's plug in the coordinate point (3,5) and see what our k value is,

\(\Large\rm 5=\dfrac{k}{3}\)
What do you get for k? c:

Answer 5

3 ? O: @zependrix

Answer 6

@zepdrix

Answer 7

5 equals k divided by 3
5 equals one third of k
So we need to multiply the 5 by 3 to find our k.

lol zependrix XD

Answer 8

15? @zepdrix

Answer 9

And hahah i typed it wrong xD

Answer 10

Ok great! k=15,
Plugging that in gives us,
\(\Large\rm y=\dfrac{15}{x}\)

Answer 11

Ok so the answer is k= 15/x right? But is it vary directly or inderectly? @zepdrix

Answer 12

Indirectly right? @zepdrix

Answer 13

you -_-
you and your ways.. -_-

no not k=15/x,
look back at what i just wrote :d
direct or indirect?
You should be able to find tht info from my first post D:

Answer 14

Oh I called it an `inverse relationship`, sorry.
that's another word for `indirect`.

Answer 15

See it is indirect -.- lol but 15 right? @zepdrix
