**constant**greater than zero and is called the

**constant**of variation.

Hereof, which equation is a direct variation function?

Direct variation function is defined as the relation where one variable vary **constant** times to the other variable. let two variables are x and y. y = kx where k is **constant**. y = x is direct variation function where k = 1.

Also Know, what is another name for direct variation? **Direct Variation**. Directly Proportional. A relationship between two variables in which one is a constant multiple of **the other**. In particular, when one variable changes **the other** changes in proportion to the first. If b is directly proportional to a, the equation is of the form b = ka (where k is a constant).

Beside this, which is an example of a direct variation?

Some **examples** of **direct variation** problems in real life: The number of hours you work and the amount of your paycheck. The amount of weight on a spring and the distance the spring will stretch.

How do you solve for direct variation in K?

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.
