    No and Yes.

    Step-by-step explanation:

    The inequation is y ≥-x+7 and the pair is (x, y) = (-1,-1). Then:

    -1≥ - (-1) + 7

    -1 ≥ 1+7

    -1 ≥ 8, but this is not true, so (-1,-1) is not a solution of y ≥-x+7.

    On the other hand, the inequation is y> (3/4) x-5 and the pair is (5,3). Then:

    3> (3/4) (5) - 5

    3> (15/4) - 5

    3> - 5/4 and this is true, so (5,3) is a solution of y> (3/4) x-5.
