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
Hint:
A trend line on a graph, also called a line of best fit, is a line that portrays the overall trend of the points on the graph. The goal of a trend line is to minimize the distance between each individual point and the trend line itself.
The correct answer is: 18 chapters
The scatter plot shows the relationship between the number of chapters (y axis) and the total number of pages for several books ( x axis).
Plot the line which coincides with 180 ( y axis) on the x axis
Thus, there will be 18 chapters in a book with 180 pages.
