Answer:

B

Step-by-step explanation:

the equation that represents x and y in direct variation is

y = kx ← k is the constant of variation

given

6y = 12x ( divide both sides by 6 )

y = 2x ← in the form y = kx

This equation represents direct variation with the constant k = 2

Final answer:

The given equation 6y = 12x represents a direct variation, and the constant of variation is 2.

Step-by-step explanation:

The given equation 6y = 12x represents a direct variation. In direct variation, two values are directly proportional to each other, meaning that a change in one value results in a proportional change in the other. The constant of variation, denoted as k, represents the ratio between the two variables. For the given equation, we can rewrite it as y = 2x, which shows that the constant of variation is 2.
