Question

Interpreting Initial Value
Mr. Lopez, a Language Arts teacher, has his students read a certain number of pages out loud in class to start a book, and then a set number of pages for homework each night to complete the book. The graph displays the total number of pages read each day.

A graph has days on the x-axis and pages read on the y-axis. Points are at (0, 35), (1, 57), (2, 79), (3, 101), (4, 123).

What does the point (0, 35) represent?
The students will read 35 pages a day to complete the book.
The book begins on page 35.
None of the students read 35 pages.
The students read 35 pages in class to start the book.

Answer 1

The students read 35 pages in class to start the book.

Explanation: (0,35) is the total pages read at day 0 (initial value). Each day after they add 22 pages (57−35), so the 35 pages were read in class at the start.
