Equations from Unit Rates

Activity Overview

This lesson involves finding a linear equation and confirming the equation represents a proportional relationship with numeric values in ordered pairs or in functions tables.

Objectives

  • Students will compute unit rates.
  • Students will find linear equations using unit rates to represent proportional relationships.
  • Students will examine ordered pairs to confirm that linear equations represent proportional relationships.

Vocabulary

  • ordered pair
  • unit rate
  • linear relationship
  • proportional relationship

About the Lesson

This lesson involves finding a linear equation and confirming the equation represents a proportional relationship with numeric values in ordered pairs or in functions tables.
As a result, students will:

  • Find the linear relationship given a proportional situation.
  • Find ordered pairs on the linear equation.
  • Find numeric value that fit the proportional situation.
