Let \"h%2Aw\" = the circumference
\n" ); document.write( "Let \"w\" = width
\n" ); document.write( "---------------
\n" ); document.write( "\"2h+%2B+2w+%3C=+180\" ft
\n" ); document.write( "also,
\n" ); document.write( "\"w+%3C=+30\"
\n" ); document.write( "\"2h+%3E=180+-+2w+\"
\n" ); document.write( "\"h+%3E=+60\"
\n" ); document.write( "-------------
\n" ); document.write( "\"0+%3C+w+%3C=+30\"
\n" ); document.write( "\"60+%3C=+h+%3C+90\"
\n" ); document.write( "--------------
\n" ); document.write( "When \"w+=+0\", \"h+=+90\"
\n" ); document.write( "when \"w+=+30\",\"h+=+60\"
\n" ); document.write( "--------------
\n" ); document.write( "I'll plot \"w\" on the horizontal axis
\n" ); document.write( "and \"h\" on the vertical
\n" ); document.write( "so, I have the points
\n" ); document.write( "(0,90) and (30,60)
\n" ); document.write( "using the point-slope formula,
\n" ); document.write( "\"%28h+-+60%29%2F%28w+-+30%29+=+%2890+-+60%29%2F%280+-+30%29\"
\n" ); document.write( "\"%28h+-+60%29%2F%28w+-+30%29+=+-1\"
\n" ); document.write( "\"h+-+60+=+30+-+w\"
\n" ); document.write( "\"h+=+-w+%2B+90\"
\n" ); document.write( "I will plot this:
\n" ); document.write( "The only part of the line that is valid is the part inside
\n" ); document.write( "\"0+%3C+w+%3C=+30\"
\n" ); document.write( "\"60+%3C=+h+%3C+90\"
\n" ); document.write( " \"+graph%28+400%2C+400%2C+-20%2C+120%2C+-20%2C+120%2C+-x+%2B+90%29+\"\r
