Question

the population of a country was 127,202,630 in 1930 and 283,421,913 in 2000. use the ordered pairs (0,127 million) and (70,283 million) to find and interpret the slope of the line representing the average rate of change in the population. the slope of the line through the points (0,127 million) and (70,283 million) is approximately 2.23 million. (round to the nearest hundredth as needed.) choose the correct interpretation of the slope. a. the population is decreasing at an average rate of about 0.45 million people per year. b. the population is increasing at an average rate of about 0.45 million people per year. c. the population is increasing at an average rate of about 2.23 million people per year. d. the population is decreasing at an average rate of about 2.23 million people per year.

Explanation:

Step1: Analyze slope sign and value

The slope is positive (2.23), so population increases.

Step2: Match to correct interpretation

Slope = 2.23 million per year, so population increases at this rate.

Answer:

C. The population is increasing at an average rate of about 2.23 million people per year.
