Answer
$X_{max}=3,X_{min}=-3,Y_{max}=2,Y_{min}=-2,X_{scl}=1,Y_{scl}=1.$
Work Step by Step
As we can see on the figure: $X_{max}=3,X_{min}=-3,Y_{max}=2,Y_{min}=-2.$
There are $6$ sections on the "x-axis", hence $X_{scl}=\frac{X_{max}-X_{min}}{6}=\frac{3-(-3)}{6}=1.$
There are $4$ sections on the "y-axis", hence $Y_{scl}=\frac{Y_{max}-Y_{min}}{4}=\frac{2-(-2)}{4}=1.$
Thus $X_{max}=3,X_{min}=-3,Y_{max}=2,Y_{min}=-2,X_{scl}=1,Y_{scl}=1.$
