## Reflection: Rigor Introduction to a System of Linear Equations - Section 3: Closure

When reflecting on this lesson, I wanted students to visually see more examples of systems of equations with non-linear equations as well.  So, I have added another closure activity as an optional activity depending on the level of the class.  My intention is to increase rigor throughout this unit when possible.  The additional closure is a calculator activity to find the solutions of a system of nonlinear functions.  It could also be used as an extension for higher level students.
