Answer
See below.
Work Step by Step
If we select:
$X_{min}$ to be lower than all x-coordinates of the points (e.g., $-3$);
$X_{max}$ to be greater than all x-coordinates of the points (e.g., $7$);
$Y_{min}$ to be lower than all y-coordinates of the points (e.g., $−4$);
$Y_{max}$ to be greater than all y-coordinates of the points (e.g., $9$);
and set $X_{scl}=1,Y_{scl}=1$; then we get a good solution.
