Linear Functions

A linear function is a special type of function which involves constant change in x - y values. In this concept, we learn to identify, graph and solve linear functions. We also learn about intercepts, slopes, and various forms of the equation of a line.

The concept is broken into smaller topics, which makes it easier and much more fun for students. The topics are listed below:-

Equations of Direct Variation

In this topic, we learn to identify and form a direct variation equation. We also learn to solve some application problems based on this.
