# Suppose that y varies inversely with x, how do you write an equation for the inverse variation y=4 when x=-6?

May 31, 2017

The inverse variation equation is $x \cdot y = 24$
$y$ varies inversely with $x$ , so
y prop 1/x :. y =k *1/x or x*y=k; k is a constant of proportionality.
 y=4 ; x=6 :. k =x*y=4*6=24
The inverse variation equation is $x \cdot y = 24$ [Ans]
