Finding the X Coordinate of Intersection of Two Equations by Graphing

This video tutorial teaches how to find the X coordinate of the intersection of two equations by graphing them. It reviews the concept of solutions to equations and systems of equations, emphasizing the importance of the intersection point. The lesson also covers the slope-intercept form, highlighting common misunderstandings. A real-world example involving cell phone plans is used to illustrate the application of these concepts, showing how to determine when two plans cost the same by graphing their respective equations.

What is the correct way to represent the cost structure of a cell phone company using equations?

How can you graph the equations of two different cell phone companies to find when their costs are equal?
