Solving Systems of Equations by Graphing

Solving Systems of Equations by Graphing

Author: James Bailey

Upon completion of this lesson, students will be able to

(1) substitute an ordered pair into a given system of equation and determine whether the ordered pair is a solution to the system or not.

(2) graph a system of equations and identify common points as the solution(s) to the system.

This lesson will begin by defining a system of linear equations and solution to a systme of linear equations. It moves onto identifying ordered pairs as either being solutions to linear equations or not being solutions of linear equations. Finally, students learn to graph linear systems and identify the solution from the graph.

Success Packet - Lesson 5.1-Solving Systems of Equations by Graphing

This packet includes guided notes, practice problems, and a sample quiz for lesson 5.1.


Lesson 5.1 - Determine whether an ordered pair is a solution to a system of linear equations

In this lesson, we learn how to substitute ordered pairs into systems of equations. If the ordered pairs satisfy both equations, we say the ordered pair is a solution to the system.

Lesson 5.1 B - Solving systems of Linear Equations by Graphing

In this video, we learn how to graph the lines included in a system of equations and find their point of intersection. We report this point as the solution to the system.
