The manager at a local Verizon store kept track of daily sales of the iPhone 7 when it was first introduced. He noticed that sales were very high at first, but showed a steady decrease. For example, on day 3 after the phones first went on sale, the store sold 290 iPhone 7s, but on day 9 after the phones first went on sale, the store sold only 164 iPhone 7s. Assume that the relationship between number of days since the phone became available and number sold is linear and, let x = the number of days since the phone was released and y = number of phones sold at this Verizon store.

a) Write two ordered pairs to represent the sales on the days described.

b) Find the slope of the line through those ordered pairs.

c) Write an equation in point-slope form of the line.

d) Convert the equation to slope-intercept form.

e) Explain what the slope and the y-intercept mean in the context of this problem.
