Graph the inequality
\n" ); document.write( "4x + y is greater than or equal to 4
\n" ); document.write( " $\"4x%2By%3E=4\"$
\n" ); document.write( " $\"4x-4x%2By%3E=-4x%2B4\"$
\n" ); document.write( " $\"y%3E=-4x%2B4\"$
\n" ); document.write( "Plot points the way you would an equality.
\n" ); document.write( "Let x=0 and solve for y:
\n" ); document.write( " $\"y=-4%280%29%2B4\"$
\n" ); document.write( " $\"y=0%2B4\"$
\n" ); document.write( " $\"y=4\"$ Plot (0,4)
\n" ); document.write( "Let x=1 and solve for y:
\n" ); document.write( " $\"y=-4%281%29%2B4\"$
\n" ); document.write( " $\"y=-4%2B4\"$
\n" ); document.write( " $\"y=0\"$ Plot (1,0)
\n" ); document.write( "Because the inequality contains =, connect the two points with a solid line like this:
\n" ); document.write( " $\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2C-4x%2B4%29\"$
\n" ); document.write( "I don't have the capability of shading this graph for you, but you would shade above the line because y is greater than the rest of the graph.
