Questions 2-8. Consider the variation of temperature with altitude depicted in the graph below. Variation of temperature (°F) with altitude 62.0 60.0 |0, 60.0 58.0 56.0 54.0 52.0 50.0 48.0 46.0 5000, 42.0 44.0 42.0 40.0 500 1000 1500 2000 2500 3000 3500 4000 4500 5000 5500 6000 altitude (feet above sea level) Write a sentence to explain what the slope means. The temperature drops 0.0036 degrees for every foot above sea level. The altitude drops 0.0036 degrees for every degree increase in temperature. The temperature increases 0.0036 degrees for every foot above sea level. The altitude increases 0.0036 degrees for every degree decrease in temperature. Temperature

Please answer part c, show work. Please be right. Thx.

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
