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)
