RS has endpoints at R(-6, 3) and S(1,6). Find the midpoint M of RS. Write the coordinates as decimals or integers

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.

Bis the correct answer
