Answer: not proportional
Explanation:
The constant is called the coefficient of proportionality if one variable is always the product of the other variable and a constant. And the variables are said to be directly proportional.
In the given table , let the variables are proportional then the constant of proportion(k)=

=1.5
=1.45
⇒ k is not a constant of proportionality.
⇒ the variables x and y are not proportional.
