Now the dog is in a park. Draw a graph that tells this story:

- The dog starts at distance and time of zero. His owner throws a ball.

- His runs for 8 meters at a steady pace of 2 meters/second.

- He accelerates back to his owner, who is holding a treat (this takes 3 seconds)

- He sits still for 5 seconds to eat the treat

- Finally, he walks away 5 meters at 1m/second

Please add a title, both axes labelled with units, and a line of motion that matches the story.
