Explanation:
Assume the graph looks like the one below.
It shows that, from Point B to C, the distance they were from home did not change. They had stopped.

If they had slowed their walk, BC would still point up. However, its slope would be less than that of AB.
If they had returned home, BC would point down and to the right.
