Inverse variation means the product of the two measurements is constant.

y=3 when x=4 means the product xy=12.

So your second value of y is 12 divided by whatever your second value of x is.

An inverse variation can be represented by the equation => or . That is, varies inversely as if there is some nonzero constant such that, or where ,

If varies inversely as , we have

and if when , you can find

then
