Tutorial

## Video of the Lesson

There is only one example in the "Guided Practice" segment. You should have your graphing calculator available and follow the steps to ensure that you know how to enter data, create a scatter plot and find a linear model for a set of data.

## Assignment

1) Complete the "Review" problems from the beginning of the lesson.

2) Write a summary of the lesson. Use proper grammar, spelling, punctuation and complete sentences.

## In Class

The next time we meet in class we will complete the "Spyglass Activity". Also, we will complete the assignment below. You may get started on it ahead of time if you'd like.

Pg. 20-21 #20, 25, 29, 31, 33

*For #29, 31 and 33, you should also find a linear model (equation for the line of best fit) for each set of data. The directions in the book do not instruct you to do this, but I'm adding it to the assignment.
