The diameter and circumference of a circle.
Direct variation.
The relationship between two quantities with a constant rate of change or ratio is described as a linear relationship. In this case, the quantities can be expressed in the form of an equation, typically (y = mx + b), where (m) represents the constant rate of change (slope) and (b) is the y-intercept. If the ratio of the two quantities is constant, they are also said to be directly proportional, meaning that as one quantity increases or decreases, the other does so in a consistent manner.
In mathematics, two quantities are proportional if they vary in such a way that one of them is a constant multiple of the other.
In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities.
ratio
Proportional
The answer is proportional.
Two quantities are said to be proportional if they vary in such a way that one of the quantities is a constant multiple of the other, or equivalently if they have a constant ratio.
The corresponding sides of similar solids have a constant ratio.
It is a direct proportion.
Two variables whose ratio is constant have a linear relationship. The first variable is the second multiplied by the constant.

A linear relationship
It is called the constant of proportionality.
The relationship is a linear one. For example when driving at a constant speed, the relationship between distance driven and the time driven is linear with a constant ratio (of the constant speed).
