x1 y1 x2 y2
\n" ); document.write( "5 4 7 8
\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "(8-4)/(7-5)
\n" ); document.write( "( 4 / 2 )
\n" ); document.write( "m= 2
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point (5,4) in
\n" ); document.write( "Y = m x + b
\n" ); document.write( "4.00 = 10 + b
\n" ); document.write( "b= 4 - 10
\n" ); document.write( "b= -6
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y=2x-6
