AX+BY=C SUBTRACT AX FROM BOTH SIDES
\n" ); document.write( "BY=-AX+C NOW DIVIE ALL TERMS BY B
\n" ); document.write( "Y=-AX/B+C/B
\n" ); document.write( "-------------------------------------

\n" ); document.write( "(Y2-Y1)/(X2-X1)
\n" ); document.write( "EXAMPLE (3,5)(-1,-7)
\n" ); document.write( "(-7-5)/(-1-3)
\n" ); document.write( "-12/-4=3 WHICH IS THE SLOPE OF AS LINE THROUGH THESE TWO POINTS.
