This is Activity 11 from the EXPLORATIONS Book:
EasyData Activities: Modeling Algebraic Functions with Data Collection Activities.

The following materials are required for this activity:
• Stored data from Activity 10: Two Hot, Two Cold

## Inverse of Two Temps

#### Activity Overview

Students find a conversion equation that will calculate the corresponding Celsius temperature for any given Fahrenheit temperature. Students learn to graph scatter plots, analyze and graph linear equations, compute and model slope, derive and apply a conversion equation, and analyze inverse relations.

#### Key Steps

• Students will import data from previous activity and set up a scatter plot of Celsius vs. Fahrenheit temperatures.

• Students will model the data using a linear regression. Equations from both temperature activities are then graphed with the line Y=X in order to explore the symmetry between a linear function and its inverse.
