    Yes, but the last part is confusing. The f(x,y)

    Did you get a graph like the one above?

    Once you have the graph, pick out the points that make up the corner of the region, then plug them into f(x, y). For example, \[f(3, 6)=9(3)+5(6)=27+30=57\]

    f(4,2)=9(4)+5(2)=36+10=46?

    f(9,9)=9(9)+5(9)=81+35=116

    So the maximum would be 9,9?
