To predict the population in the year 2030 using the given trend line equation, we substitute the value of x as 30 (since 2030 is 30 years after 2000):
y = 0.83x + 30
y = 0.83(30) + 30
y = 24.9 + 30
y = 54.9
Therefore, the predicted population in the year 2030 is approximately 54.9 million people.
opulation growth of a state since 2000 in millions of people is represented by a linear
•1. Using the trend line, y = 0.83x + 30, predict the population, y, in the year 2030. Let 30 because the year 2030 is 30 years after the year 2000.
