Chapter 1: Variations
What you need to learn in this chapter
In the 'Variations' chapter, we will be learning about direct variation, inverse variation, and combined variation. Direct variation refers to a relationship between two variables where one variable increases or decreases in direct proportion to the other. We will learn how to determine the relation between two variables for a direct variation. Inverse variation, on the other hand, is a relationship where one variable increases while the other decreases, or vice versa. Lastly, combined variation involves both direct and inverse variation in the same equation. We will explore how to solve problems involving combined variation.
