You can put this solution on YOUR website!
how do you solve and graph this inequality:
\n" ); document.write( "y > (1/2)x - 1
\n" ); document.write( "--------------------
\n" ); document.write( "You never graph an inequality directly.
\n" ); document.write( "You 1st of all graph the corresponding
\n" ); document.write( "boundary EQUALITY.
\n" ); document.write( "----
\n" ); document.write( "Graph y = (1/2)x -1 as a dashed line.
\n" ); document.write( "If x = 0, y = -1
\n" ); document.write( "If x = 2, y = 0
\n" ); document.write( "------------------------
\n" ); document.write( "Plot the points (0,-1) and (2,0)
\n" ); document.write( "and draw a dashed line thru them.
\n" ); document.write( "That is the boundary line.
\n" ); document.write( "-----------------------------------
\n" ); document.write( "Since you want y to be LESS than (1/2)x -1,
\n" ); document.write( "shade the half-plane BELOW the boundary line.
\n" ); document.write( "========================================
