Step 1. Look at the graph. The left-handside of the graph (total sales in dollars)is called the vertical axis because itstarts at the bottom corner and pointsup. The bottom of the graph (days ofthe week) is called the horizontal axisbecause it starts at the bottom cornerand points across to the right.

Step 2. Because you are looking for twodays on which sales were the same, lookfor two points of the same height. Checkalong the vertical axis to make sure thesales totals are the same. Look along thehorizontal axis to find the days onwhich sales were the same.

Sales were the same on Wednesday and Thursday.
