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.
