determine the correct half-plane in each case and complete the graph
\n" ); document.write( "4x+y>4 (the symbol > has an underline)
\n" ); document.write( "-------------------------
\n" ); document.write( "4x+y >= 4
\n" ); document.write( "y >= -4x+4
\n" ); document.write( "----------------------
\n" ); document.write( "!st: Graph the EQUALITY which is the boundary for INEQUALITY:
\n" ); document.write( " $\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C-4x%2B4%29\"$
\n" ); document.write( "-----------------------------
\n" ); document.write( "2n: Select a point that is not on the boundary to be a test point.
\n" ); document.write( "for example select (0,0)
\n" ); document.write( "Put those value into the INEQUALITY to see if that point is or is
\n" ); document.write( "not part of the solution:
\n" ); document.write( "0 > -4*0 + 4
\n" ); document.write( "0 > 4
\n" ); document.write( "That is false so shade the half-plane on the side that does not
\n" ); document.write( "contain (0,0); that would be the half-plane above the boundary.
