Answer:
The given points are
[tex](-13,3)\\(0,0)\\(-2,-7)[/tex]
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
[tex]x_{min}=-15\\x_{max}=2\\ y_{min}=-9\\y_{max}=5[/tex]
With a scale of 2 units.
