The equations of the two lines are y=2 (the horizontal one) and y=x (the diagonal line).
The region is 'under' y=x without including such line, and 'above' y=2 without including that line.
Therefore, the system of inequalities whose solution is the shaded region is
[tex]\begin{gathered} y>2 \\ and \\ yThus, the answer is y>2, y
