Question

8. Between 1980 and 1990, the population of Naples, Florida increased by

Answer 1

Answer:

The correct option is B

y = 6,000x + 80,000

Step-by-step explanation:

Given that between 1980 and 1990, the population of Naples, Florida increased by approximately 6000 people per year. In 1980, the population was 80,000.

This is a linear equation of the form y = mx + c

Here m is the slope = 6,000

And c is the constant value = 80,000.

We then simply have

y = 6,000x + 80,000

Answer 2

Answer:

y = 6,000x + 80,000

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.
