The following scatter plot shows the relationship between the weekly number of hours of watching television and the weekly number of hours spent gardening:
A graph is titled Television and Hours Spent Gardening. On the x axis, the label is Weekly Hours Spent Gardening 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 0,9 and 1,10.5 and 2,8 and 3,7 and 4,6 and 5,5.2 and 6,4 and 7,3.8 and 8,3 and 9,1.8 and 10,2.5. A line joins the ordered pairs 0, 9.65 and 10, 1.4.
What is the y-intercept of the line of best fit and what does it represent? (1 point)
11.5 hours; the number of hours students garden when they do not watch television
9.65 hours; the number of hours students garden when they do not watch television
9.65 hours; the number of hours students watch television when they do not garden
11.5 hours; the number of hours students watch television when they do not garden
9.65 hours; the number of hours students watch television when they do not garden
This is because the y-intercept is the value of y when x=0, which in this case is the number of hours of watching television when the number of hours spent gardening is 0.
