A librarian collected data on the number of pages in chapters of a book. Interpret the slope and the y -intercept of the linear model. Round the slope to the nearest hundredth.
The slope of the linear model represents the rate of change of the number of pages in a chapter. In this context, the slope would indicate how many pages increase or decrease per unit change in chapters.
The y-intercept of the linear model represents the number of pages in a chapter when the chapter number is zero. In this context, it would represent the base number of pages when the book starts.
For example, if the linear model is y = 1.25x + 20, the slope would be 1.25, indicating that for every one unit increase in chapter number, the number of pages increases by 1.25. The y-intercept would be 20, indicating that the book starts with 20 pages in the first chapter.
