The expression that represent proportional relationship has the form:


y=kx

where k is the constant of proportionality.

In this case we are looking for a relationship of the form:


y=-2x

or something equivalent. If we multiply both sides by two we get:


2y=-4x

Those two are the relations that fulfill the conditions given.
