The population of a town has grown by an average of 2,000 people per year over the last 10 years. Which equation could represent an appropriate linear model

of the population?

A.) y = 25,000x + 2,000

B.) y = 2,000x + 25,000

C.) y = -25,000x + 2,000

D.) y = -2,000x + 25,000

of the population?

A.) y = 25,000x + 2,000

B.) y = 2,000x + 25,000

C.) y = -25,000x + 2,000

D.) y = -2,000x + 25,000

**In slope-intercept form, y = mx + b:**

**m is the slope or rate of change**

**b is the y-intercept or, in this case, the starting amount**

If the town is growing by an average of 2,000 people per year, then 2,000 is the rate of change.

x is the number of years

Based on the answer choices, it appears the starting amount is 25,000

**B.) 2,000x + 25,000**
