Hello, dhiab!
These are strange problems . . .
Solve in
The line has intercepts (4,0) and (0,4). Code:

* 
*
 *
 *
 *
  +    *  
 *

We have the inequality: .
This is true when and have opposite signs.
There are two cases: .
The graph looks like this: Code:
::::::::
::::::::
::::::::
::::::::
    2+      
::::::::::
+:::::
::::::::::
::::::::::
::::::::::
Together, we have this graph . . . Code:
::::*:::
::::::*:
::::::::*
:::::::: *
    2+  *    
:::::*:::::::
+::::*:::
:::::::::*:::
:::::::::::*:
:::::::::::::*
The final graph looks like this: Code:
* 
* 
*

2+  *    
 *
+*
 *
 *
 *
How can we describe this graph?
Maybe: .
