You can put this solution on YOUR website! Y Is Equal To Or Less Than X+2
----
1st: Graph the boundary: y = x+2
Plot two points:
(0,2) and (2,2)
Draw a line thru them.
that is the boundary:
=========================================
2nd: Since you want y Less than x=2
shade the half-plane BELOW the boundary:
=============================================
