In this lesson, you will write a system of equations to represent the quantities and constraints in each of several situations, find a solution that meets multiple constraints by graphing, and then interpret the solution in context.

When you finish this lesson, you will be able to:

• Explain “the solution to a system of linear equations” and how the solution is represented graphically.
• Refer to two equations as a system of equations.
• Use tables and graphs to solve systems of equations.

Here are the activities that will help you reach those goals:

• 2.1.1: Understanding Constraints and Values
• 2.1.2: Writing and Graphing Equations
  • 2.1.2: Self Check
  • 2.1.2: Additional Resources
• 2.1.3: Meeting Constraints
  • 2.1.3: Self Check
  • 2.1.3: Additional Resources
• 2.1.4: Exploring a System of Equations

After that, you’ll practice and review.

• 2.1.5: Practice
• 2.1.6: Lesson Summary
