During the spring and summer, a concession stand at a community little league baseball game field sells soft drinks and other refreshments. to prepare for the season, the concession owner refers to the previous year's files, in which he had recorded the daily soft drinks sales (in gallons) and the average daily temperature (in degrees fahrenheit). using the coordinates of the two points (84,80) and (74,65), determine the slope of the line of best fit.

  1.5

Step-by-step explanation:

The slope is given by ...

  (change in dependent variable)/(change in independent variable)

  = (65 -80)/(74-84) = -15/-10 = 1.5

The slope of the line of best fit is 1.5.

The slope of the line of best fit is 1.5 degrees Fahrenheit per gallon.

Step-by-step explanation:

If a line passes through two points and , then the slope of the line is

The given two points are (84,80) and (74,65).

The slope of the line of best fit is

Therefore the slope of the line of best fit is 1.5 degrees Fahrenheit per gallon.
