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.
graph:
chapters: 0, 3, 4, 5, 8, 10, 12, 17, 18, 20
pages: 0, 20, 41, 45, 99, 90, 130, 160, 170, 210
A: every chapter of a book, there is an average of 1/10 page.
B: every chapter of a book, there is an average of 0.1 page.
C: every chapter of a book, there is an average of 10 page.
D: every chapter of a book, there is an average of 1 page.
The slope of the linear model is approximately 10, which means that for every additional chapter in the book, there are on average 10 more pages.
The y-intercept of the linear model is at (0,0), which means that if the book had 0 chapters, it would have 0 pages.
