Graphs of Systems of Linear Inequalities in Two Variables: President Jefferson's Octagonal Home

Curated and Reviewed by Lesson Planet
This Graphs of Systems of Linear Inequalities in Two Variables: President Jefferson's Octagonal Home interactive also includes:
  • Systems of Inequalities: An Explanation
  • Systems of Inequalities: An Application
  • Student Reference
  • Join to access all included materials

Mathematically complete a set of blueprints. Using eight linear inequalities, pupils create a blueprint of Thomas Jefferson's home. Individuals graph the linear inequalities and position the solution of the inequalities before identifying different shapes formed by subsets of the eight inequalities.
