Question is in picture.

Answer:
17 Units
Step-by-step explanation:
So first you find the distance of -7 from -2, which is 5.
For the Y-Axis, you find the distance of -5 to 0, which is 5, then you find the distance of 0 to 7, which is 7.
You add them up, and get 12.
To finish, you add 9 and 12 and get 17.
