Congratulations to those of you who correctly answered this
problem. Holly from Stoke by Nayland Middle School sent in this
solution:  If the man gets closer to his house then the graph
line gets lower and lower.  The slower the man walks the more
curvy the line gets, if the man goes away from the house really
slowly and then really slowly towards the house then you can
make a curvy line.  To make it steeper you have to make him go
faster and then when you are on the bend you stay still for a
bit to make it smoother.  Dominic gives a concise answer:  To
curve steeper you would have to walk faster and to curve
shallower you would have to walk slower.
