Lesson Description:

Know what the two parameters in a linear model/function mean in the context of real relationships. Recognize the vocabulary used for these parameters depending on the context constant rate / slope / coefficient and initial value / vertical intercept / constant.

- Currently 5.0/5 Stars.
This lesson tries to move you away from a line looking like y = mx + b. Using full functional notation, a function can use any letters to represent the input and output as well as the parameters. Therefore, you will learn more descriptive names for the slope and y-intercept in a linear model. The problem set and solutions will help this make more sense to you.
