x1 y1 x2 y2
\n" ); document.write( "1 3 -3 8
\n" ); document.write( "
\n" ); document.write( "slope m =(y2-y1)/(x2-x1)
\n" ); document.write( "m=-1.25
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point (1,3) in
\n" ); document.write( "Y =mx+b
\n" ); document.write( "3.00=-1.25+b
\n" ); document.write( "b= 3 +1.25
\n" ); document.write( "b= 4.25
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y =-1.25x +4.25
\n" ); document.write( "
\n" ); document.write( "
