# Assume that y varies inversely as x, how do you write an inverse variation equation that relates x and y given y=-6 when x=-3?

The inverse variation equation is $x y = 18$
y prop 1/x or y = k* 1/x or xy=k ; x =-3 ; y = -6 :. (-3)*(-6)=k or k=18 or xy=18
The inverse variation equation is $x y = 18$ [Ans]
