Solve the following inequalities graphically in two-dimensional plane:

y < – 2


Given: y < – 2

Consider: y = – 2


Now draw a dotted line y = – 2 in the graph ( y = – 2 is excluded in the given question)


Now Consider y < – 2


Select a point (0,0)


0 < – 2


0 < 30 (this is false)


Solution region of the given inequality is below the line y < – 2. (That is Away from the origin)


The graph is as follows:
