Create two ordered pairs where the -coordinate is the year number where zero represents 1990 and then add one for each year after that and the -coordinate is the associated number of workers.

With the two ordered pairs you just created, use the Two-Point Form of an equation of a line to derive the desired equation.

Using x=0 for year 1990, the description gives two points:
(0, 525000) and (16, 491).

You could setup the raw equation as y=%28%28491-525000%29%2F%2816-0%29%29x%2B525000.
Simplify.
