Is this an inverse relation....  2x+4y=6

Explain?

anonymous · Answer

We usually are asked if two functions are inverses, or find the inverse. Is there more to this question?

anonymous · Answer

No...

anonymous · Answer

Have you been working with functions being inversely proportional?

anonymous · Answer

Um I don't think so.... we've been working with inverse variations.

anonymous · Answer

ok, that is what I needed. When a function varies inversely, it can be written as $$y = {k \over x}$$

If we solve this function for y, we get

$$2x+4y=6$$$$4y=-2x+6$$$$y = {-2 \over 4}x+{6 \over 4}$$

which isn't in the same form as y = k/x so this function is not an example if inverse variation.

OK?
