first, you want to start with the b (-3) graph on the y-axis. after that, since your x is 2 you will start from -3 on the y-axis and go up 2 and to the left once and keep doing that till you run out of space. then go back to the -3 on the y-axis and go down 2 and to the right once
Answer:
The given points are

The setting would have a interval or 2 units above and below the minimum and maximum of each coordinate.
The given maxium horizontal coordinate is 0.
The given minimum horizontal coordinate is -13.
The given maximum vertical coordinate is 3.
The given minimum vertical coordinate is -7.
Now, we extend each maximum and minimum value by 2 units to create the setting.
So, the setting is

With a scale of 2 units.
