Chad is investigating how long his phone's battery lasts (in hours) for various brightness levels (on a scale of 0-100). His data is displayed in the table and graph below. Hours Brightness Level (x) Hours (y) 21 29 7.4 38 51 73 80 90 92 5.7 4.1 4.4 3.9 4.1 1.9 0.1 11+ 10 9 8 7 6 + 3 2 1 10 20 30 -1 40 50 60 70 80 90 100 11 Brightness Level a) Find the equation for the line of best fit. Keep at least 4 decimals for each parameter in the equation. b) Interpret the slope in context. Chad should expect -0.0684 hours per brightness level. ○ Chad should expect -0.0684 brightness level per hour. c) What does the equation predict for the number of hours the phone will last at a brightness level of 80? hours d) What is the residual for the point (80,4.1)? hours
