Elliot collected the air temperature and the water temperature at a local river for seven days. His data is displayed on the scatter plot 80 70 . Water Temperature (°F) 60 50 60 70 80 Air Temperature (°F) The equation of the line of best fit is y = 0.5% + 25, where i is the air temperature and v is the water temperature. What is the meaning of the slope of the line of best fit? A The water temperaturhis expected to be 0.5 °F less than the air temperature. B. The water temperature is expected to be 0.5 °F greater than the air temperature. C. When the air temperature increases by 1 'F, the water temperature is expected to decrease by 0.5 °F. D. When the air temperature increases by 1 °F, the water temperature is expected to increase by 0.5 °F.​
