1 Four Faces of a Linear Function Saving for an iPhone

2 Today we will…  Define Linear Relationship  Discuss the Four Faces of a Linear Function  Summarize the iPhone Investigation

3 Definition of a Linear Relationship  Comparison of two variables that change at constant rates.

4 Four Faces of a Linear Function  Table  Graph  Equation  Story Problem

5 Table

6 Graph

7 Equation

8 Story Problem

9 How can we see a linear relationship in each of the four faces of a function?  Table ~ both the independent and dependent variables will increase or decrease at a constant rate  Graph ~ line (Linear)  Equation ~ will be in the form of y = mx + b; the equation will be in the first degree  Story Problem ~ will contain a constant; look for the word “per” in the story problem
