Activity Overview

Students use linear functions to model and solve problems in situations with slope and a constant rate of change. They learn to represent situations with variables in expressions, equations, and inequalities and use tables and graphs as tools to interpret them.

Before the Activity

  • See the attached PDF file for detailed instructions for this activity
  • Print pages 38 - 42 from the attached PDF file for your class

    		•

    		During the Activity

    		Distribute the pages to the class.

    Follow the activity procedures:
  • Given the coordinates of two points, use the slope formula to find the slope of the line passing through the two points
  • Change the decimal result to a fraction


  • For each given ordered pair of numbers, plot the points, draw a line through the points, and find the slope of the line
  • Solve a real world problem and understand the meaning of the slope in the given situation


  • Make a plot of the data pairs from the given problem, draw a line through the pairs, and use the linear model to predict results


  • Write an equation to model given data, use the equation to generate several data pairs, plot the points, and find answers

    		After the Activity

    		Students complete the Student Activity pages.

  • Review student results
  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
