Corresponding values of two variables x and y
If there is any relation of variation between x and y, let us write it by understanding.
Answer :
Given:
We see in the given table, as the value of x increases or decreases the corresponding value of y is also decreasing or increasing respectively.
i.e. xy = 54 = constant
Hence, 
and here value of variation constant is 54.
Here, the value of variation constant is positive. i.e. for value of A increases or decreases the corresponding value of B will also decreases or increases respectively.
