How to determine if points are collinear or noncollinear

The video tutorial explains how to determine if points are collinear, meaning they lie on the same line. It provides examples of collinear points, such as points D, B, and E, and points A, B, and C. The tutorial also discusses the concept of intersection, where point B is collinear for both lines, and highlights non-collinear points that do not lie on the same line.

Explain why points E and A are considered non-collinear.
