Four Faces of a Linear Function Saving for an iPhone
Today we will… Define Linear Relationship Discuss the Four Faces of a Linear Function Summarize the iPhone Investigation
Definition of a Linear Relationship Comparison of two variables that change at constant rates.
Four Faces of a Linear Function Table Graph Equation Story Problem
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
