Find the midpoint between (9,6)and (5,8)

Finding the midpoint is like finding the average. (9+5)/2=7 for x and (6+8)/2=7 for y so the midpoint is (7,7)

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
