B. 11.1 hours; the number of hours students spend time with friends in a week when they do not watch television
C. 6.9 hours; the number of hours students spend time with friends in a week when they do not watch television
D. 11.1 hours; the number of hours students watch television in a week when they do spend time with friends

Answer 1

Answer:

A

Step-by-step explanation:

Since the graph is described in the comments as "line joining (0,6.9) and (10,0.75)", the line crosses through the point (0,6.9) on the y-axis. This is the y-intercept so 6.9 is the intercept value.

The graph is labeled with the y-axis as hours spent watching TV. So 6.9 hours is the number of hours watching TV and 0 hours spent with friends.

Answer 2

Answer:

6.9 hours; the number of hours students watch television in a week when they do not spend time with friends.
