Let $\"+r+\"$ = number of red beads
\n" ); document.write( "Let $\"+b+\"$ = number of black beads
\n" ); document.write( " $\"+1%2Ar+%2B+.5%2Ab+=+20+\"$ ( standard form )
\n" ); document.write( " $\"+r+=+-.5b+%2B+20+\"$ ( slope intercept form )
\n" ); document.write( "---------------------
\n" ); document.write( "Here's the plot of $\"+r+=+f%28b%29+\"$
\n" ); document.write( " $\"+graph%28+400%2C+400%2C+-4%2C+45%2C+-3%2C+25%2C+-.5x+%2B+20+%29+\"$ \n" ); document.write( "
