Question
Solve the following inequality graphically in two-dimensional plane:
Solution
First, we draw the dark line to represent the graph of x - y = 2
x 0 2
y -2 0
Now, let us take a point O(0, 0)
Substitute in given inequality which is not true.
Therefore, origin is not the solution of given inequality.
From these observations, the graph is given below, in which the shaded portion represents the solution of the given inequality.
