Question

which equivalent ratio proportional relationship with the constant proportionality equals -2 select all that apply

Answer 1

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.
