The population growth of a city since 1900 is represented by a linear model. Interpret the slope and the y -intercept.

The slope of the linear model represents the rate of population growth per unit of time. It indicates how much the population of the city is increasing or decreasing over a given period. If the slope is positive, it means the city's population is growing, and if the slope is negative, it means the population is decreasing.

The y-intercept of the linear model represents the initial population of the city in the year 1900. It is the value of the population when the time is zero (at the beginning of the given time period).
