Linear Regression Warm-up 3/7/23

This is question 3 on page 5 of your packet.

The table shows the number of graduating seniors at a high school. Let 0 = 2012, 1 = 2013, 2 = 2014, 3 = 2015, 4 = 2016, and 5 = 2017

What is the line of best fit for the data set? Round all coefficients to the nearest hundredth. WRITE DOWN YOU THE EQUATION AS IT WILL BE USED FOR THE NEXT QUESTION!

• y = 9.17x - 18114.70

• y = 9.17x + 338.24

• y = 9.171x + 338.238

• y = 9.171x - 18114.700

If 0 = the year 2012, what x-values represents the year 2025?

• 2025

• 2012

• 12

• 13
