Question

4.

Answer 1

The x axis should be time periods and since the range of months is in 3 months, the increments should be every 3 months.

The y-axis should be the sales and since most of the amounts are in 6 digits, we use increments of $100,000.

Therefore, the answer is the 3rd options:
x-axis: time period in increments of 3 months; y-axis: sales in increments of $100,000
