Use general point-slope formula
\n" ); document.write( " $\"+%28+y+-%28-1%29+%29+%2F+%28+x+-+3+%29+=+-2+\"$
\n" ); document.write( " $\"+%28+y+%2B+1+%29+%2F+%28+x+-+3+%29+=+-2+\"$
\n" ); document.write( " $\"+y+%2B+1+=+-2%2A%28+x-3+%29+\"$
\n" ); document.write( " $\"+y+%2B+1+=+-2x+%2B+6+\"$
\n" ); document.write( " $\"+y+=+-2x+%2B+5+\"$
\n" ); document.write( "-------------------
\n" ); document.write( "check:
\n" ); document.write( "does it go through ( 3,-1 )
\n" ); document.write( " $\"+-1+=+-2%2A3+%2B+5+\"$
\n" ); document.write( " $\"+-1+=+-6+%2B+5+\"$
\n" ); document.write( " $\"+-1+=+-1+\"$
\n" ); document.write( "OK \n" ); document.write( "
