Answer:
Constant of propotionality is 0.25.
Direct proportionality means that the dependence between the two variable, x and y in this case, is such that the quotient of those two variables is constant.
y/x=0.25 . Quotient of x and y is constant so we can say that x and y are directly proportional.
