Inequalities are used to describe unequal expressions.
The inequality of the shaded region is: 
The boundary line is given as:

Divide through by 2

Make y the subject

The shaded region is above the boundary line (see attachment)
This means that, we make use of the greater than sign (>)
So, we replace = with >

As a standard form, we have:

Hence, the inequality of the shaded region is:
