To determine how many points should be plotted when creating a scatterplot from the provided data, you need to count the pairs of values listed in the table. Each pair corresponds to a point in the scatterplot, where one value represents the number of pages in the book and the other represents the time needed to read the book.
From the data provided, here are the pairs of values:
- (200 pages, 18 hours)
- (175 pages, 15 hours)
- (275 pages, 21 hours)
- (225 pages, 18 hours)
- (400 pages, 30 hours)
- (350 pages, 26 hours)
There are 6 pairs of values, which means you should plot 6 points in total for the scatterplot.
