x1 y1 x2 y2
\n" ); document.write( "9 8 -2 1
\n" ); document.write( "
\n" ); document.write( "slope m =(y2-y1)/(x2-x1)
\n" ); document.write( "(1-8)/( -2-9)
\n" ); document.write( "(-7/-11 )
\n" ); document.write( "m=0.64
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point (2, -4) in
\n" ); document.write( "Y =mx+b
\n" ); document.write( "-4.00=1.27+b
\n" ); document.write( "b=-4-1.27
\n" ); document.write( "b=-5.27
\n" ); document.write( "So the equation will be
