The population growth of a city since 1900 is represented by a linear model. Interpret the slope and the Y intercept.
For every year since 1900, the population grew by approximately 650. In 1900, the population was 20,000.
For every year since 1900, the population grew by approximately 1590. In 1900, the population was 20,000.
For 0.65 of a year since 1900 the population grew by approximately 1000. In 1900, the population was 20,000.
Forever every year since 1900, the population group by approximately 300. In 1900 the population was 0
In the first scenario, the slope of the linear model is 650, which means that for every year since 1900, the population of the city grows by 650. The Y intercept is 20,000, which represents the population of the city in the year 1900.
In the second scenario, the slope of the linear model is 1590, which means that for every year since 1900, the population of the city grows by 1590. The Y intercept is 20,000, which again represents the population of the city in the year 1900.
In the third scenario, the slope of the linear model is 1000, which means that for 0.65 of a year since 1900, the population of the city grows by approximately 1000. The Y intercept is 20,000, representing the population of the city in the year 1900.
In the fourth scenario, the slope of the linear model is 300, which means that for every year since 1900, the population grows by 300. The Y intercept is 0, which is likely an error as it is not possible for a city to have zero population in the year 1900.
