Find the constant of variation k for the inverse variation. Then write an equation for the inverse variation.

y = 4.5 when x = 3

A.  k = 13.5; xy = 13.5

B.  k = 1.5; y = 1.5x

C.  k = 1.5; y = 1.5/x

D.  k = 13.5; 13.5y = x

For an inverse variation  xy = k

therefore k= (3)(4.5) = 13.5

A.  k = 13.5; xy = 13.5
