Points P and R are located at (2, 1) and (12, -15) respectively. Point M is the midpoint of segment PR. Segment PR is reflected over the x-axis. What is the sum of the coordinates of the image of point M (the midpoint of the reflected segment)?

Coordinates of reflected points
P' = ( 2, -1) R' = ( 12 , 15)
Midpoint of P'R' = [ (2 + 12) / 2 , ( 15 -1) / 2 ] = ( 14/2, -14/2) = ( 7 , -7)
