    Y = 2x-9 (8,7)

    7 = 2 (8) - 9

    7 = 16-9

    7=7

    Yes, since the equation is true on both sides after solving it.

    Yes (8,7) does make the equation true. 8 is the x value and 7 is the y. Plug these into the equation. So you would have 7=2 (8) - 9 simplify to get 7=16-9 and the final answer is 7=7, which makes the equation true.
