determine the correct half-plane in each case and complete the graph
4x+y>4 (the symbol > has an underline)
-------------------------
4x+y >= 4
y >= -4x+4
----------------------
!st: Graph the EQUALITY which is the boundary for INEQUALITY:
-----------------------------
2n: Select a point that is not on the boundary to be a test point.
for example select (0,0)
Put those value into the INEQUALITY to see if that point is or is
not part of the solution:
0 > -4*0 + 4
0 > 4
That is false so shade the half-plane on the side that does not
contain (0,0); that would be the half-plane above the boundary.
=====================
