7x+3y=21
\n" ); document.write( "y int is when x=0, (0,7)
\n" ); document.write( "x int is when y=0, (3,0)
\n" ); document.write( "7(0)+3y=21
\n" ); document.write( "y=7
\n" ); document.write( "-----------------
\n" ); document.write( "7x+3(0)=21
\n" ); document.write( "x=3
\n" ); document.write( "Does that help?
