$-500$ per year The number of news reporters and correspondents employed by the United States decreases by 500 per year.

Work Step by Step

In 2008, the United States employed $62,000$ news reporters and correspondents. In 2018, the United States is expected to employ $57,000.$ To find the rate of change in the number of news reporters and correspondents employed by the United States, divide the change in the number of employed news reporters and correspondents by the time: $=\dfrac{57000-62000}{2018-2008 \text{ years}}=\dfrac{-5000}{10\text{ years}}= -500$ per year
