The line of best fit in the scatterplot above represents the relationship between elevation and temperature. Which of the following statements best interprets the slope of this line in context?
For every 1000-foot increase in elevation, the temperature is predicted to increase by approximately 2°F.
For every 1-foot increase in elevation, the temperature is predicted to decrease by approximately 500°F.
For every 500-foot increase in elevation, the temperature is predicted to decrease by approximately 1°F.
The temperature is predicted to be 44°F at an elevation of 0 feet.
