    Let's check choice A (−5, 9) (x + 6)y = 9 (-5 + 6)*9 = 9 ... replace x with -5 and y with 9 (1)*9 = 9 9 = 9 ... this is true, so choice A (−5, 9) is a solution I'll let you check the others. There may be more than one answer

    (3, 1) (x+6)y = 9 (3+6) * 1 = 9 (1) * 9 = 9

    (-3,3) (x+6)y = 9 (-3 + 6) * 9 = 27 (1) * 27 = 27 27 = 9 :( wrong

    replace 9 with 27, which means b is right so it was a, b, and c

    then you replace the `-3+6` part with `3` since `-3+6 = 3`

    D (7,9) (x + 6)y = 9 (7 + 6)*9 = 9 13*9 = 9 117 = 9 ... false so you are correct about D
