Question

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. A) for every 10 chapters of a book, there is an average of 1 page. B) for every chapter of a book, there is an average of 0.1 page. C) For every chapter of a book, there is an average of 1/10 page. D) For every chapter of a book, there is an average of 10 pages.

Answer 1

B) for every chapter of a book, there is an average of 0.1 page.

Interpretation:
- Slope: 0.1
The slope represents the average change in number of pages for each additional chapter in the book. In this case, the slope of 0.1 means that on average, for each chapter added to the book, there is an average increase of 0.1 page.

- Y-intercept: The y-intercept in this case would not have a practical interpretation since it does not start at 0, which would have been the case if it represented 0 pages for 0 chapters.
