Proportionality Constant Calculator

Enter two values to calculate the constant of proportionality (k) in the direct variation equation y = kx.

x

The independent variable.

y

The dependent variable.

Constant of Proportionality (k)

Visualizing Proportionality

The relationship is represented by:

y = x

This equation shows that y varies directly with x. For every unit increase in x, y increases by units.

Given values: x = , y =

Understanding Proportionality Constant

In mathematics, particularly in the context of direct variation, the proportionality constant (k) is the ratio between two variables that are directly proportional. If we say 'y varies directly as x', it means that y is directly proportional to x. This relationship can be expressed by the equation:

y = kx

Here, 'k' is the constant of proportionality. It remains constant regardless of the values of x and y. To find 'k', you can rearrange the formula to:

k = y/x

This calculator helps you quickly determine the value of 'k' when you have a pair of corresponding values for x and y in a direct variation scenario. Direct proportionality is a fundamental concept in various fields, including physics, engineering, and economics, to describe relationships where one quantity changes in direct proportion to another.
