Characteristics of Linear and Non-Linear Graphs

The video tutorial explains how to determine if a graph is linear or non-linear. A linear graph is represented by a perfectly straight line with no curves, stops, or starts. In contrast, a non-linear graph includes curves or changes in direction. The video provides examples of both types, illustrating how to identify them based on their characteristics.
