Unit 4, Lesson 9# An Application of Linear Equations

EngageNY 45 min(s)

Students know how to rewrite an exponential expression that represents a series as a linear equation. The purpose of this lesson is to expose students to applications of linear equations. The Discussion revisits the Facebook problem from Module 1 but this time in the context of a linear equation. This is an opportunity to highlight MP.1 (Make sense of problems and persevere in solving them), as the Discussion requires students to work with equations in ways they have not before.
