Answer :

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem

we have

y=x+4 ------> is not proportional (the line not passes through the origin

y=x/4 ----> is a proportional relationship (the value of k is 1/4)

y=4x ----> is a proportional relationship (the value of k is 4)

y=
