Understanding and Solving Systems of Linear Equations (Grade 8)

This lesson set is designed to provide students opportunities to extend their previous understanding of linear equations to include systems of linear equations. Students develop and solidify an understanding of what it means to be a solution to a system, how to use a context, tables, graphs, and/or equations to determine the solution set of a system, and the conditions under which a system has zero, one, or infinitely many solutions. 

Through engaging in this lesson set, students will:  

• analyze what it means to be a solution to a system of equations;  
• solve a system graphically, using a table of values, and algebraically; and  
• develop an understanding of the conditions under which a system that consists of two linear equations has zero, one, or infinitely many solutions.
