The population of Rock Springs is growing at a constant rate. The expression represents the increase in population in x years.

45,200 + 1,900x

How much does the population increase each year?

A) 0

B) 1,900

C) 45,200

D) 47,100

1,900

The function is given by

y=45,200 + 1,900x

and is of the form y = mx+b, where m is the rate of change and b is the fixed value (or we can say initial value)

Now when we compare we get m = 1,900 for our problem.

So the population increases every year by 1,900.
