Last Updated: 19th April, 2020

**constant of variation**is the number that relates two variables that are directly proportional or inversely proportional to one another.

Moreover, how do you find the constant variation?

Since k is **constant** (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the **constant of variation** is k = = 3. Thus, the **equation** describing this **direct variation** is y = 3x.

Also Know, what is the meaning of variation in math? **Variation**. **Variation** problems involve fairly simple relationships or **formulas**, involving one variable being equal to one term. When one variable increases the other decreases in proportion so that the product is unchanged.

Just so, what is a constant in math?

A fixed value. In Algebra, a **constant** is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are constants. See: Variable. Algebra - Definitions.

How do you find the variation in math?

**To calculate the variance follow these steps:**

- Work out the Mean (the simple average of the numbers)
- Then for each number: subtract the Mean and square the result (the squared difference).
- Then work out the average of those squared differences. (Why Square?)
