Answer
$X_{max}=6,X_{min}=-6,Y_{max}=4,Y_{min}=-4,X_{scl}=2,Y_{scl}=2.$
Work Step by Step
As we can see on the figure: $X_{max}=6,X_{min}=-6,Y_{max}=4,Y_{min}=-4.$
There are $6$ sections on the "x-axis", hence $X_{scl}=\frac{X_{max}-X_{min}}{6}=\frac{6-(-6)}{6}=2.$
There are $4$ sections on the "y-axis", hence $Y_{scl}=\frac{Y_{max}-Y_{min}}{4}=\frac{4-(-4)}{4}=2.$
Thus $X_{max}=6,X_{min}=-6,Y_{max}=4,Y_{min}=-4,X_{scl}=2,Y_{scl}=2.$
