x1 y1 x2 y2
\n" ); document.write( "0 -1 2 3
\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "(3-(-1))/(2-0)
\n" ); document.write( "(4/2)
\n" ); document.write( "m=2
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point (0,-1) in
\n" ); document.write( "Y =mx+b
\n" ); document.write( "-1.00=0+b
\n" ); document.write( "b=-1+0
\n" ); document.write( "b=-1
\n" ); document.write( "So the equation will be
