Show the solution set of the following in equations by graphical method:
x – 2y < 0
To find the solution set for x – 2y < 0 graphically, we first draw x – 2y = 0
which is a dotted line passing through the origin (as seen from the
graph). x – 2y < 0 is represented as a shaded region above x – 2y = 0,
excluding all the points lying on the line x – 2y = 0.
