Step 1

When two variable quantities have a constant ratio, their relationship is called a direct variation. It is said that one variable varies directly as the other. The formula for direct variation is , where is the constant of variation.

Step 2

Solve the equation for , the constant of variation.

Step 3

Replace the variables and with the actual values.

Step 4

Use the direct variation model to create the equation.

Step 5

Substitute the value of into the direct variation model.

Step 6

Simplify the result to find the direct variation equation.
