  1. are we looking at two inequalities:
    y^2/4 - x^2.25 ≤ 1
    y ≥ 2x/3 + 4 ??

    What about them? are we graphing their intersection?

    if so, ...
    x^2/4 - y^2/25 = 1 is a hyperbola
    so
    x^2/4 - y^2/25 ≤ 1
    would be the region "inside" the hyperbola
    see:
    http://www.wolframalpha.com/input/?i=+x%5E2%2F4+-+y%5E2%2F25+≤+1+

    and of course y = 2x/3 + 4 is a straight line,
    and y ≥ 2x/3 + 4 is the region above and including the line

    So we want the region between the curves of the hyperbola and above the line y = 2x/3 + 4 , including the points on the curves and the line.
