x1 y1 x2 y2
\n" ); document.write( "-1 -4 4 11
\n" ); document.write( "
\n" ); document.write( "slope m =(y2-y1)/(x2-x1)
\n" ); document.write( "(11+4)/( 4+1)
\n" ); document.write( "(15/5)
\n" ); document.write( "m=3
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point(-1,-4 ) in
\n" ); document.write( "Y = m x + b
\n" ); document.write( "-4.00=-3 +b
\n" ); document.write( "b=-4-3
\n" ); document.write( "b=-1
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y =3x-1
