Evan 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. Brightness Level (x) 17 26 30 35 36 37 45 94 Hours (y) 6.7 5.9 5.8 4.5 6.8 6.1 3.8 2.1 10203040506070809010011012345678910-1Brightness LevelHours 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. Evan should expect -0.0604 hours per brightness level. Evan should expect -0.0604 brightness level per hour. c) What does the equation predict for the number of hours the phone will last at a brightness level of 36? hours
