From the graph,
[tex]y = \frac{1}{2}x + 2[/tex]
But this one is inequality so you gotta remember this:
When y > x/2+2
- The shade/region is above the graph itself.
When y < x/2+2
- The shade/region is below the graph.
Therefore, the inequality as shown in the picture is
[tex]y > \frac{1}{2} x + 2[/tex]
