    Answer:

    (-6, 7) is NOT on the given circle

    Step-by-step explanation:

    Write out the standard equation of a circle with center at (h, k) and radius r:

    (x – h)^2 + (y – k)^2 = r^2, where (h, k) is the center and r is the radius.

    Substituting 2 for h and -9 for k, and 5 for r, we get

    (x – 2)^2 + (y + 9)^2 =5^2

    Now determine whether or not the point (-6, 7) is on this circle:

    Substituting -6 for x and 7 for y, we get:

    (-6 – 2)^2 + (7 + 9)^2 =5^2    Is this true or false?

    64 + 256 = 225?  NO.  Thus, (-6, 7) is NOT on the given circle.
