x1 y1 x2 y2
\n" ); document.write( "1 -5 -3 7
\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "( 7 - -5 )/( -3 - 1 )
\n" ); document.write( "( 12 / -4 )
\n" ); document.write( "m= - 3
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point ( -1 , 8 ) in
\n" ); document.write( "Y = m x + b
\n" ); document.write( "8.00 = -3 + b
\n" ); document.write( "b= 11
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y = -3 x + 11
