x1 y1 x2 y2

\n" ); document.write( "
\n" ); document.write( "x1 y1 x2 y2
\n" ); document.write( "5 -12 8 12
\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "( 12 - -12 )/( 8 - 5 )
\n" ); document.write( "( 24 / 3 )
\n" ); document.write( "m= 8
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point ( 5 , -12 ) in
\n" ); document.write( "Y = m x + b
\n" ); document.write( "-12.00 = 40 + b
\n" ); document.write( "b= -12 - 40
\n" ); document.write( "b= -52
\n" ); document.write( "So the equation will be
