To plot a point in the cartesian plane, we have to consider the x-entry of the point and find that number in the real line that corresponds to x, then we consider the y-entry of the point and we find that value in the real line that corresponds to the y values.
In this case, the points to graph are:
A=(5.5,15.6),
AA=(5.4,14.8),
B=(8,23.6),
BB=(8,23.2),
C=(3,10),
CC=(3.1,8.8),
D=(4,12),
DD=(4,11.6),
E=(6.7,20),
EE=(6.5,23.2),
F=(10.5,29.6),
FF=(10.5,30),
G=(2,6),
H=(12.5,36.8),
I=(5.7,16).
