This module was designed and written with you in mind. It is here to help you master the skills of graphing systems of linear equations in two variables. You are provided with varied activities to process the knowledge and skills learned and to deepen and transfer your understanding of the lesson. The scope of this module enables you to use it in many different learning situations. The lessons are arranged to follow the standard sequence of the course. But the order in which you read them can be changed to correspond with the textbook you are now using.

This module contains:

Lesson 1- Graphing Systems of Linear Equations in Two Variables

After going through this module, you are expected to:

1. describe the graph of the systems of linear equations in two variables as parallel, intersecting, or coinciding;

2. determine through graphs whether the system is consistent and independent, consistent and dependent, or inconsistent;

3. appreciate the use of graphs of the systems of linear equations as basis for making decisions; and

4. graph systems of linear equations in two variables.
