The scatterplot shows the temperature, in degrees Fahrenheit (), and the distance above sea level, in feet, measured at 6 locations on Mount Jefferson. A line of best fit is also shown.
The x-axis represents distance above sea level, and the y-axis represents temperature.
Which of the following best describes the meaning of the slope of the line of best fit in the context of this scatterplot?
The predicted temperature at sea level.
The average change in temperature for each 1,000-foot increase in distance above sea level.
The total range of temperatures observed.
The distance above sea level where the temperature is 0 .
