AU2 Linear Functions

Unit 2

Key Learning:
The graph of a linear equation is a visual representation of its infinite solutions.

Unit Essential Question:
How does knowing the slope of a line help in writing the equation of the line and graphing the line?

Concept 1: Graphing Constant & Linear Functions	Concept 2: Writing Constant & Linear Functions	Concept 3: Modeling with Linear Regression
Lesson Essential Questions: How do you find the slope of a line and use it to describe the line or the relationship between lines? How do you graph linear functions and identify their characteristics?	Lesson Essential Questions: How do you write the equation of a line? How do you know whether two variables vary directly?	Lesson Essential Questions: How do you describe the correlation of a set of data? How do you use linear regression to approximate a line of best fit for a set of data?
