TODAY IN ALGEBRA 2.0…  Warm up: Drawing and calculating the line of best fit  Learning Goal 1: 2.6 (Part 2) You will fit lines to data in scatter plots  Independent Practice-Assignment #6  COE – if time

WARM UP: On the half sheet, calculate the slope and y-intercept to create a line of best fit.

2.6 SCATTER PLOTS-FITTING LINES TO DATA x01234567 y280295322395425471511548

2.6 SCATTER PLOTS-FITTING LINES TO DATA: Linear regression using a graphing calculator x01234567 y280295322395425471511548 Using the previous EXAMPLE:

2.6 SCATTER PLOTS-FITTING LINES TO DATA: Linear regression using a graphing calculator x012345678 y666065606470645062505880582058005750 PRACTICE: The table shows the U.S. daily oil production y(in thousands of barrels) x years after 1994.

2.6 SCATTER PLOTS-FITTING LINES TO DATA: Linear regression using a graphing calculator PRACTICE: The data pairs (x,y) give the population y(in millions) of Texas x years after 1997. Approximate the best- fitting line for the data.
