Question

Predict which of these equations represents a proportional relationship.

a) y=4+x
b) y=4x
c) y= 4/x
d) y= x/4

​

Answer 1

The equation y=4x represents a proportional relationship.

Step-by-step explanation:

A proportional relationship exists between two quantities when they vary in such a way that one of the quantities is a constant multiple of the other. In other words, as one quantity changes, the other changes in a consistent and predictable manner.

Out of the given equations, the equation y=4x represents a proportional relationship. In a proportional relationship, two values are directly proportional when a change in one leads to the same change in the other. The equation y=4x is in the form y=kx, where k is the proportionality constant.
