Direct Variation Calculator

Formula

To calculate the Constant of Direct Variation ( $C$ ):

$C = \frac{X}{Y}$

Where:

$C$ is the Constant of Direct Variation
$X$ and $Y$ are Coordinate Points

What is Direct Variation?

A direct variation is defined as the relationship between two dependent variables. That is, each variable is directly proportional to the other variable at a constant rate. The form $y = cx$ is also the point-slope form of a line.

Example Calculation 1

Let's assume the following values:

Coordinate $X$ = 10
Coordinate $Y$ = 2

Using the formula:

$C = \frac{10}{2} = 5$

The Constant of Direct Variation is 5.

Example Calculation 2

Let's assume the following values:

Coordinate $X$ = 15
Coordinate $Y$ = 3

Using the formula:

$C = \frac{15}{3} = 5$

The Constant of Direct Variation is 5.
