Slope and Interpreting Graphs

The scatter plot shows the relationship between the number of chapters and the total number of pages for several books.  Use the trend line to predict how many chapters would be in a book with 180 pages. 

• 12 chapters

• 15 chapters

• 18 chapters

• 21 chapters

As x increases, y decreases.

• no correlation

• negative correlation

• correlation coefficient

• positive correlation
