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.

(1 point)

For every 2 chapters of the book, there is an average of 5 pages.

For every 5 chapters of the book, there is an average of 30 pages.

For every 10 chapters of the book, there is an average of 100 pages.

For every 2 chapters of the book, there is an average of 10 pages.

Answer 1

I don’t have the actual linear equation or the slope/intercept values from your model. I can’t pick one of those four choices without that.

How to decide:
- The slope = change in pages per chapter (pages per 1 chapter). To convert to any option phrased “for every k chapters, there is an average of m pages,” multiply the slope (pages per chapter) by k and compare to m.
- The y‑intercept = the predicted number of pages when the chapter number is 0 (a baseline — e.g., front matter or the model’s starting value).

If you paste the linear model (or the slope and intercept), I’ll convert it into the matching choice.
