x + 2y < 7
y >= -x -1

You can't type that?

Graph
x + 2y = 7 and
y = -x -1
They're straight lines, so you need 2 points each.
For x + 2y < 7, it's the area below the line, not including the line.
---
For y >= -x -1 it's the area above the line including the line.
The solution is the overlapping areas.
