Understanding Points of Intersection of Linear Functions

The video tutorial explains how to determine the point of intersection of two linear functions using both graphical and algebraic methods. It begins by introducing the concept of intersection points and the slope-intercept form of linear equations. The tutorial then demonstrates how to graph the functions to find the intersection point, highlighting the importance of accuracy. It also covers solving the equations algebraically by setting them equal to each other and solving for the variables. The tutorial concludes by confirming that both methods yield the same intersection point.
