Hello!
The key word in this is After walking 5 steps forward, Julie walked 5 steps backward
So, she walked forward 5 steps, then walked back the same steps, returning her to her starting position.
your answer is the second graph.
This graph shows what i explained: she starts at 0. goes forward 5, then back 5, returning her to 0.
I hope this helps, and have a nice day!
