A convenience store manager notices that sales of soft drinks are higher on hotter days, so he
assembles the data in a table shown below.

High Temperature (F)
55, 58, 64, 68, 70, 75, 80, 84

Cans sold:
340, 335, 410, 460, 450, 610, 735, 780

10) Use the data to find a line of best fit.

11) What does the model predict for the number of cans sold for a high temperature of 70?

12) Is the predicted number of cans lower or higher than the actual cans sold on a day with a high temperature of 70?
