The graph shows the number of units produced in a factory over five months of a year. Determine the difference in the number of units produced in February and May.

Let’s look at this graph that we’ve been given more closely. It’s a line graph, and the month is on the horizontal axis, and the number of units produced each month is on the vertical axis.

To determine the difference in the number of units produced in February and May, we first need to read off the values for the number of units produced in each month individually. If we read across to the vertical axis from the point for February, the value here is 5000.

This means that the factory produced 5000 units during February. If we read across to the vertical axis from the point for May, the value here is 2000. So the number of units produced in May is 2000. To find the difference, we need to subtract 2000 from 5000.

The difference in the number of units produced in February and May is 3000 units.
