## Direction Variation Formula

The following formula is used for calculating a direction variation.

C = X/Y

Y= CX

- Where C is the constant of direction variation
- X and Y are coordinate points.

In this case the form y= cx is also the point slope form of a line. Just as with the line form, i direct variation may have a constant b, associated with it.

## Direct Variation Definition

A direct variation is defined as the relationship between two dependent variables. That is each variable depends on the other.

## How to calculate direct variation?

How to calculate direct variation?

**First, determine the constant of direct variation.**This is C is the formula above.

**Next, determine one of the coordinate points of x or y.**Determine the value of one variable.

**Finally, calculate the missing variable.**Using the formula above, calculate the missing variable using direct variation.

## FAQ

**What is a direct variation?**

A direction variation is a relationship between two variables. Typically this is described in the form of a line equation like y=cx, where c is the direct variation constant.

**When can direction variation be used?**

Direction variation can be used in any situation that involves one or more variables. For example, if you have two variables A and B that are directly related, then you can figure out their values at any point in time. Let’s say for every point A increase B increase 2 points. This means that if A=4 then B =8.
