    Hello, norwoodjay!

    Graph the solution set of the system of inequalities.

    28) .x + y .< .4
    . . . .x -2y .> .6

    The line x + y .= .4 has intercepts (4,0) and (0,4).
    . . Plot the intercepts and draw the line.
    . . Shade the region below the line.

    The line x - 2y .= .6 has intercepts (6,0) and (0,-3).
    . . Plot the intercepts and draw the line.
    . . Shade the region below the line.

    The graph looks like this:
    Code:
          * |
          4 o
            | *
            |   *
            |     *
            |       * 4         *
      - - - + - - - - o - - o - - - - - -
            |          .*.  6
            |      .*:::::*.
            |  .*:::::::::::*.
         -3 o:::::::::::::::::*.
        *:::|:::::::::::::::::::*
            |
