Answer:

(9
(1)/(2), 5
(1)/(2)) or (9 1/2, 5 1/2) (same things, just typed two different ways)

Explanation

I can't remember the midpoint formula so I'll use a different method to get the midpoint.


since the ratio of a midpoint is 1:1 and that as a fraction is 1/2, we can take these coordinates and designate which one is first and which one is second (12, 2) will be my second and (7,9) will be my first. The formula I will use will be
(m)/(m+n) (second X, - first X) + first x, so 1/2( 12 - 7) +7. now distribute the 1/2 to both the numbers
(1x12)/(2) -(1x7)/(2) + 7 \\ \\ 12/2 -7/2 = 5/2 + 7 = 9.5 or
9(1)/(2). The same works with the Y values, which would equal up to 5.5 or 5
(1)/(2)
