8. Between 1980 and 1990, the population of Naples, Florida increased by
attashe74 [19]

Answer:

<h2>y = 6,000x + 80,000</h2>

Step-by-step explanation:

Givens

  • The population increased 6000 people per year. (This is the constant ratio of change, because it offers information about the relation between variables).
  • In 1980, the population was 80,000. (This is the initial condition, the population at the beginning of the period, that's why is the y-intercept of the function).

We know that the linear form has an explicit form

y=mx+b

Where m is the constant ratio of change and b is the y-intercept. Replacing given values, we have

y=6,000x + 80,000

Therefore, the right answer is B.
