Answer:

If the given equation is

y = 6x

comparing with y = kx

so k = 6

Thus, option C is correct.

Step-by-step explanation:

We know when y varies directly with x, with a constant of variation k

then the equation is

y ∝ x

y = kx

where k is the 'constant of proportionality.

k = y/x

  • Given that the value of k=6

If the given equation is

y = 6x

comparing with y = kx

so k = 6

Thus, option C is correct.
