Bell Work Monday 11/10/14 scatter plot shows the • Today’s Objective: Linear The relationship between the day of the Regression month and a frozen yogurt stand’s daily profit during the month of July. • Materials: Calculator, Springboard Book, P 3 1. Draw the scatter plot on the right onto graph paper 2. Is the data linear? Explain.

Bell Work Tuesday 11/11/14 • Today’s Objective: Linear Regression • Materials: Calculator, Springboard Book, P 3 • Use the same scatter plot from Monday. 1. Draw a trend line on the scatter plot and name two points that your trend line passes through. 2. Write the equation of the trend line you drew in Item 1 3. What do the variables in your equation represent? 4. What is the slope of the trend line? What does this tell you?

Bell Work Wednesday 11/12/14 • Today’s Objective: Unit 2 Embedded Assessment 3: A 10 K Run (Page 207) • Materials: Springboard Book, Calculator, Planner & Pencil • When the bell rings, get your book and planner out, and we will begin as soon as everyone is done talking. • It is a test, so NO TALKING (or I will take 5 points off, plus a D-Hall)

Bell Work Thursday 11/13/14 • Today’s Objective: Unpacking EA 2 Unit 3 • Materials: Calculator, Springboard Book, P 3 • Use the same scatter plot from Monday. 1. Use your trend line to predict the yogurt stand’s daily profit on July 20 th. 2. The owner of a competing frozen yogurt stand finds that her daily profit each day in July is exactly $100 more than that of the stand in the scatter plot. Write the equation of a trend line for the competing stand.

Bell Work Friday 11/14/14 • Today’s Objective: Solving Systems of Linear Equations • Materials: Calculator, Springboard Book, P 3 1. Graph the lines y = x - 2 and y = 2 x - 6 on the same coordinate plane. 2. What are the coordinates of the point of intersection? • Turn in your bell work, when you finish. • Begin 17 -1 on Page 251 • As a whole class, read the Learning Targets and the Scenario about the Two Truckers. • Summarize what is going on with the truckers. • As groups, answer questions 1 through 8.
