Impossible to tell from your rendering.

is direct variation.

is inverse variation. And your rendering could be interpreted either way. Next time you post, use parentheses to eliminate any ambiguities.

would be y = (4/9)x

Wheras:

would be y = 4/(9x)

The constant of proportionality is

in either case.
