Which is an example of a direct variation?

*

A. ky = 10

B. y =2/x

C. y = 5x

D. 2/y = x

An example of direct variation is:

**C. y = 5x**

In a direct variation, \( y \) varies directly with \( x \), which means that if \( x \) increases, \( y \) increases in proportion. This relationship can be expressed as \( y = kx \), where \( k \) is a constant (in this case, \( k = 5 \)).

Would you like more details on direct variation or any related concepts? Here are some questions to consider:

1. What is the general formula for direct variation?
2. How can you identify direct variation from a set of points?
3. Can direct variation be represented in different forms?
4. What are some real-world examples of direct variation?
5. How does direct variation differ from inverse variation? 

**Tip:** Remember that in direct variation, the ratio of \( y \) to \( x \) remains constant.
