Solve the following pair of linear equation graphically and shade the region bounded by these lines and x - axis; also find the area of the shaded region.
2x+y=6;2xy=0

Open in App
Solution

The given equation
is 2x+y=6 and 2xy=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=62x


Now, table for 2xy=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
