option B is correct
The constant of variation is, .
Step-by-step explanation:
Since the quadratic variation is the relationship between the variables x and y
i.e, ; where k is the quadratic variation.
Given quadratic equation: Â Â ...[1]
Division property of equality states that you divide the same number to both sides of an equation
Divide both side by 9,we get
On simplifying we get;
Now, compare above equation by equation[1] we get the value of k;
i.e,
Therefore, the constant of variation is, .
