Objectives

  • Students will find the solution to a system of linear equations by hand
  • Students will use the TI-84 Plus CE to graph a linear system in two variables and find the intersection point(s)
  • Students will create and graph linear piecewise functions
  • Students will try to make a connection with how to understand these topics in IB Mathematics courses and on their final assessments

Vocabulary

  • linear system
  • piecewise function

About the lesson

This activity uses the TI-84 family handhelds as an aid to the problems, specifically graphing and analyzing piecewise and linear functions. This activity serves as a good lesson to culminate solving systems using technology.
