The equation y = 0.25x describes a proportional relationship between x and y. what is the constant of proportionality? enter your answer in the box.

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.

Hey your answer should b c

Ci want to say is right
