You can put this solution on YOUR website!
You are given 2 points:
\n" ); document.write( "( 1,0 )
\n" ); document.write( "( 0,-1 )
\n" ); document.write( "---------
\n" ); document.write( "You can plug these points into
\n" ); document.write( "the general equation:
\n" ); document.write( "\"+y+=+m%2Ax+%2B+b+\"
\n" ); document.write( "( 1,0 )
\n" ); document.write( "\"+0+=+m%2A1+%2B+b+\"
\n" ); document.write( "(1) \"+m+=+-b+\"
\n" ); document.write( "--------------
\n" ); document.write( "( 0,-1 )
\n" ); document.write( "\"+y+=+m%2Ax+%2B+b+\"
\n" ); document.write( "\"+-1+=+m%2A0+%2B+b+\"
\n" ); document.write( "(2) \"+b+=+-1+\"
\n" ); document.write( "---------------
\n" ); document.write( "Substituting:
\n" ); document.write( "(1) \"+m+=+-b+\"
\n" ); document.write( "(1) \"+m+=+-%28-1%29+\"
\n" ); document.write( "(1) \"+m+=+1+\"
\n" ); document.write( "---------------
\n" ); document.write( "The equation is:
\n" ); document.write( "\"+y+=+1%2Ax+-+1+\"
\n" ); document.write( "\"+y+=+x+-+1+\"
\n" ); document.write( "---------------
\n" ); document.write( "Here's the plot:
