    x-2y<= 4
    x>=1
    Draw the line x-2y=4, then all the points which satisfy x-2y<= 4, lie on or
    above the line.

    Draw the line x=1, then all the points which satisfy x>=1 lie on or to the
    right of the line.

    Hence all points satisfying both the inequalities lie on or above x-2y=4 and
    on or to the right of x=1.
