    Set Builder Notation? Help

    A={(9,1),(8,2),(7,3),(6,4),(5,5),(4,6),(3,7),(2,8) ,(1,9)}

    I am not sure how to write its set builder notation but I have tried it as follows

    A = {(a,b)| ai<10 and bi>0, 0<i<10}

    Any suggestion would be highly appreciated.

    I am not sure how to write its set builder notation
    A=\{(10-k,k):k=1,2,\cdots,9\}
    That is one of several ways.
