Question 319520
Please help me! How do I graph the system: 
y >= 2x+4
y <= -x+8
--------------------
1st: Graph the boundary lines.
{{{graph(400,300,-10,10,-10,20,2x+4,-x+8)}}}
----
2nd: 
1st inequality:
Since y "is greater than the boundary" shade the half-plane above it.
2nd inequality:
Since y "is less than the boundary" shade the half-plane below it.
---------
3rd: The solution is the intersection of the two shaded area and
includes the boundary of that intersection.
--------
{{{graph(400,300,-10,10,-10,20,y>2x+4,y<-x+8)}}}
==================
Cheers,
