Answer 2

answers
use a smaller range
use a larger range
delete a month

Answer 3

I suggest redrawing the graph with each of those options, and seeing what happens

Answer 4

Using a smaller range will help to widen the points on the graph along the y-axis and make the increase in sales larger.

Using a larger range will do the opposite and instead showing a small increase in sales.

Deleting a month will do nothing, if he want to portray the increase in sales. If hw want to demonstrate the volume of his sales this will be a appropriate answer.

Note that increasing and decreasing the range, will not change the number of sales he make, but rather change the graphical representation of the sales.
