3x - 7y < -21
\n" ); document.write( "-7y < -3x - 21
\n" ); document.write( "y < (-3/-7)x - (21/-7)
\n" ); document.write( "y < (3/7)x + (21/7)
\n" ); document.write( "---
\n" ); document.write( "find two points on the graph:
\n" ); document.write( "---
\n" ); document.write( "x = 0
\n" ); document.write( "y = (3/7)0 + (21/7)
\n" ); document.write( "y = 3
\n" ); document.write( "(0,3)

\n" ); document.write( "y = (42/7)
\n" ); document.write( "y = 6
\n" ); document.write( "(7,6)
\n" ); document.write( "---
\n" ); document.write( "on a piece of graph paper draw a dotted line through both points
\n" ); document.write( "---
\n" ); document.write( "the graph of the inequality is the area below the dotted line, because of the \"y <\" condition
