Q1 of 26 Page 60

Show the solution set of the following in equations by graphical method:

y ≤ –3

To find the solution set for y ≤ –3 graphically, we first draw y = – 3 which


is a line parallel to x – axis (as seen from the graph). y< – 3 is represented


as a shaded region below y = – 3, including all the points lying on the


line y = – 3.
