Systems of Equations

#### Activity Overview

In this activity, students will recognize a system of equations, determine solutions graphically, and verify solutions algebraically.

#### Objectives

• Students will recognize a system of equations.
• Students will know the definition of a system of an equation.
• Students will determine solutions to a system of equations graphically.
• Students will verify solutions to a system algebraically.
• Students will understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously.
• Students will solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations.

#### Vocabulary
