Answer
$X_{max}=7,X_{min}=-3;\\
Y_{max}=9,Y_{min}=-4;\\
X_{scl}=1,Y_{scl}=1$
Work Step by Step
IIf 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.
Thus, we can set
$X_{max}=7,X_{min}=-3;\\
Y_{max}=9,Y_{min}=-4;\\
X_{scl}=1,Y_{scl}=1$
