1. Bell Work Monday 11/10/14 Today’s Objective: Linear Regression Materials: Calculator, Springboard Book, P3 1.Draw the scatter plot on the right onto graph paper 2.Is the data linear? Explain. The scatter plot shows the relationship between the day of the month and a frozen yogurt stand’s daily profit during the month of July.

2. Bell Work Tuesday 11/11/14 Today’s Objective: Linear Regression Materials: Calculator, Springboard Book, P3 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?

3. Bell Work Wednesday 11/12/14 Today’s Objective: Unit 2 Embedded Assessment 3: A 10K 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)

4. Bell Work Thursday 11/13/14 Today’s Objective: Unpacking EA 2 Unit 3 Materials: Calculator, Springboard Book, P3 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.

5. Bell Work Friday 11/14/14 Today’s Objective: Solving Systems of Linear Equations Materials: Calculator, Springboard Book, P3 1.Graph the lines y = x - 2 and y = 2x - 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.
