The video tutorial explains how to determine if a point lies on a line given by the equation y = 1/2x + 3. It covers two methods: graphing and algebraic verification. The graphing method involves identifying the y-intercept and using the slope to plot points, while the algebraic method involves substituting the point's coordinates into the equation to check for validity. The tutorial emphasizes understanding both methods for situations where graphing is not feasible. The session concludes with a prompt for further examples.
