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.

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?
