1. 1. {(0, 10), (2, 7), (4, 5), (6, 2), (10, 1) } a. Make a scatter plot b. Describe the correlation c. Write the equation of the line of best fit

4. Tues 9/29 Lesson 2 – 7 Learning Objective: To graph absolute value functions Hw: Pg. 111 #9 - 15, *31, *34, 39 - 42

5. Algebra II

6.  To graph absolute value functions

8.  Find the vertex  Make a table, go two numbers above and below the x-value of the vertex. Plug in to find y-value  The y-values SHOULD reflect over the vertex if you found the vertex correctly  DO NOT ASSUME you have the correct vertex
