Use the image to answer the question.
A graph shows a horizontal axis representing time in weeks ranging from 0 to 10 in increments of 1. The vertical axis represents number of books read ranging from 0 to 10 in increments of 1. Two plotted points are: left parenthesis 0 comma 5 right parenthesis, left parenthesis 5 comma 8 right parenthesis. These points are joined by a straight line with arrows on both the ends.
Interpret the slope in the context of this situation. Give the most simplified rate using whole numbers.
(1 point)
Responses
A) Someone had 5 weeks to read a book.
B) Someone read 5 books in a week.
C) Someone is reading 5 books every 3 weeks.
D) Someone reads 3 books every 5 weeks.
D) Someone reads 3 books every 5 weeks.
The slope of the line connecting the two points is rise over run, which is (8-5)/(5-0) = 3/5. This means that for every 5 weeks that passes, the number of books read increases by 3. So, the most simplified rate using whole numbers is 3 books every 5 weeks.
