Remember that the equation for inverse variation is \(k = xy\).

\[\large y \alpha \dfrac{1}{x}\]

Or, equivalently, it can be expressed as\[y = \dfrac{k}{x}\]

@AravindG use `\propto` instead of `\alpha` ;)

Do you know these general forms of an inverse relation?

\[k = yx\]Here, we can plug the values \(y = 6\) and \(x = 8\). What do you think?

woah o.o i was doing something else. K=6(8)

I'd give you an example. There's an inverse relation and when \(y = 4\), \(x = 6\). The general equation would be \(k = yx\). find out \(k\), the product of all \(y\)s and the corresponding \(x\)'s.

So the general equation for my example is \(k = 24\)

It's very easy. What's the product of the \(x\) and \(y\) you're given?

Yay! That's it! :)
