A graph has air temperature (degrees Fahrenheit) on the x-axis and cups of hot tea sold on the y-axis. Points are at (0, 24), (5, 21), (10, 23), (15, 20), (20, 15), (25, 17) and (30, 12).

Question

What is the pattern displayed in the scatterplot between the number of cups of hot tea sold and the air temperature?
As air temperature increased, hot tea sales increased.
As air temperature increased, hot tea sales stayed the same.
As air temperature increased, hot tea sales decreased.
As air temperature decreased, hot tea sales decreased.

Answer 1

The pattern displayed in the scatterplot between the number of cups of hot tea sold and the air temperature shows that as air temperature increased, hot tea sales decreased. This is evident from the points provided, where higher temperatures correspond to lower numbers of cups sold. Therefore, the correct statement is:

As air temperature increased, hot tea sales decreased.
