To determine which 2-year period(s) had the smallest increase in the average salary for baseball players, you need to analyze the increments between the given years by looking at the values on the line graph. Since I don't have the visual aid of the line graph, I'll explain the process of identifying the smallest increase.
1. **Identify the Salary Values for Odd-Numbered Years**:
Assuming the values for the odd-numbered years are provided or can be estimated from the line graph, list them in a table. For instance, if these are the values (hypothetical):
| Year | Average Salary ($ millions) |
|------|-----------------------------|
| 2007 | 3.0 |
| 2009 | 3.2 |
| 2011 | 3.5 |
| 2013 | 3.7 |
| 2015 | 4.0 |
| 2017 | 4.3 |
| 2019 | 4.5 |
2. **Calculate the Increments**:
Compute the increase in salary for each 2-year period:
- From 2007 to 2009: 3.2 - 3.0 = 0.2
- From 2009 to 2011: 3.5 - 3.2 = 0.3
- From 2011 to 2013: 3.7 - 3.5 = 0.2
- From 2013 to 2015: 4.0 - 3.7 = 0.3
- From 2015 to 2017: 4.3 - 4.0 = 0.3
- From 2017 to 2019: 4.5 - 4.3 = 0.2
3. **Identify the Smallest Increase**:
From the computed increments:
- The increments are 0.2, 0.3, 0.2, 0.3, 0.3, and 0.2.
- The smallest increase is 0.2.
4. **Determine the Corresponding Periods**:
The periods with the smallest increase (0.2) are:
- From 2007 to 2009
- From 2011 to 2013
- From 2017 to 2019
Hence, the 2-year periods with the smallest increase in average salary were 2007–2009, 2011–2013, and 2017–2019.
The accompanying line graph shows how the average salary for baseball players in a certain league has increased over a 12-year period. Notice the average salary is given for odd-numbered years only. Also note that the left scale does not start at zero. Which 2-year period(s) had the smallest increase?
