What is the "Point" of Solving a System?

Unit 3: Systems of Equations
Lesson 3 of 13

Objective: Students will be able to connect to the meaning of solving a system of equations. Namely, that a line is made up from an infinite number of points that make that line's equation true. If we find a point that is on both lines that it has to make both equations true. Also that the other points on the line do not make both equations true.

Big Idea: This lesson is all about making connections between the solution to a system that students see graphically and what that solution means in terms of each equation. Students will have an opportunity to practice graphing systems of equations and showing what
