Answer
See below.
Work Step by Step
As we can see on the figure: $X_{max}=9,X_{min}=3,Y_{max}=10,Y_{min}=2. $
There are 6 sections on the "x-axis", hence $X_{scl}=\frac{X_{max}−X_{min}}{6}=\frac{9-3}{6}=1.$
There are 4 sections on the "y-axis", hence $Y_{scl}=\frac{Y_{max}−Y_{min}}{4}=\frac{10-2}{4}=2.$
