Step-by-step explanation:
We have been given that Amanda went into the grocery business starting with five stores. This means that initial value or y-intercept is 5.
We are also told that after one year, she opened two more stores. After two years, she opened two more stores than the previous year. This means that rate of change or slope is 2.
So the line representing the number of stores Amanda will own over time would be .
Upon graphing our given equation we will get our required graph as shown in the attachment.

In the question it is given that Simple interest earned from both the investments at the end of the year is $3980.
Using the given below equation, we will try to find out the investments at each rate.
x = 32000
We can calculate amount for 7% interest rate by,
(66000-32000) =34000
Thus Phyllis invested 32000 dollar at 5% interest rate and 34000 dollar at 7% interest rate.
