---------
If there is no equality sign the boundary is dotted.
If there is an equality sign the boundary is a solid line or curve.
If there is an inequality there is an area that is shaded or hatched.
------------------------------------------------------------------------
y>1
Draw a dotted horizontal line at z = 1
Shade the halfplane ABOVE because you want "greater than".
---------------
y=[x]+1
Draw a solid v-shape opening up with vertex at (0,1)
------------
The system solution is the intersection of the two graphs

---------------
2x-3<9
Draw the dotted line x = 6
Shade the halfplane to the LEFT of the line because you want "less than"
---
x+y>-2
Draw the dotted line y = -x-2
Shade the halfplane ABOVE the line because you want "greater than"
==============
The system solution is the intersection of the two graphs.

Note: This site cannot graph x = 6 because it is not a function.
