The following scatter plot shows the relationship between the weekly number of hours of watching television and the weekly number of hours spent reading: A graph is titled Television and Hours Spent Reading. On the x axis, the label is Weekly Hours Spent Reading and shows numbers from 0 to 12 at increments of 1, and on the y axis the label is Weekly Hours of Watching Television and the numbers from 0 to 12 are shown at increments of 1. Dots are made at the ordered pairs 0,11.1 and 1,9 and 2,8.1 and 3,7 and 4,7.8 and 5,6 and 6,4.8 and 7,3.8 and 8,1.8 and 9,2.1 and 10,1.3. A line joins the ordered pairs 0, 10.5 and 10, 0.94.

What is the y-intercept of the line of best fit and what does it represent?

10.5 hours; the number of hours students watch television when they do not read
