The given equation
is 2x+y=6 and 2x−y=0
Now, let us find atleast two solutions of each of the above equations, as shown
in the following tables.
Table for 2x+y=6 or y=6−2x
Now, table for 2x−y=0 or
y=2x
Here, the lines intersecting at point C (32,3)
The coordinates of the vertices of △COB are C (32, 3), O(0, 0) and B(3, 0).
Area = A = 12×base×height=12×3×3=92=4.5 sq.units
