Solve the given inequality


Solve the given inequality $x \geq y-2$ graphically in two - dimensional plane.




The graphical representation of $x \geq y-2$ is given by blue dotted line in the figure below.

This lines divides $x-y$ plane into two parts.

Select a point (not on the line), which lies on one of the two parts, to determine whether the point satisfies the given inequality or not.

We select the point as $(0,0)$

It is observed that $0>0-2$ or $0>-2$ which is false.

Therefore, the solution for the given inequality excluding the points on the line.

This can be represented as follows,
