How to determine if a point lies on a line or not using the point and the equation

The video tutorial explains how to determine if a point is on a line using the line's equation rather than a graph. It introduces the concept of a line as an infinite set of points and explains the slope-intercept form of a linear equation. The tutorial demonstrates how to test points by plugging their coordinates into the equation and verifying if the equation holds true. It also includes a practical example of testing specific points and verifying them on a graph. The tutorial concludes with a summary of the process for determining if a point lies on a line.
