Determine whether the equation represents a direct variation. if it does, find the constant of variation. -12x=6y

The equation observes direct proportionality.

Step-by-step explanation:

The condition of direct proportionality follows to this expression:

Where k is the constant of proportionality.

It is easy to conclude that equation observes the criterion of direct proportionality after some algebraic handling:

The constant of the proportionality is -2.
