How do you turn this inequality into an equation you can graph 9x-2y<-18?
\n" ); document.write( "---------------------
\n" ); document.write( "You graph the boundary of the inequality, which is the equality.
\n" ); document.write( "---
\n" ); document.write( "Solve the inequality for \"y\":
\n" ); document.write( "2y < 9x + 18
\n" ); document.write( "y < (9/2)x + 2
\n" ); document.write( "------------------------
\n" ); document.write( "Graph the boundary which is y = (9/2)x + 2
\n" ); document.write( "-----------------------------------------------
\n" ); document.write( " $\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C%289%2F2%29x%2B2%29\"$
\n" ); document.write( "--------------------
\n" ); document.write( "Now look at the inequality.
\n" ); document.write( "Since you want y to be LESS than the boundary,
\n" ); document.write( "shade the half-plane BELOW the boundary.
\n" ); document.write( "That shaded half-plane is the graph of the inequality.
\n" ); document.write( "====================================================
