Answer :

  • midpoint = (12,3)

Explanation :

The midpoint of a segment is given by,

  • midpoint = (x1 + x2)/2 , (y1 + y2)/2

plugging in,

  • midpoint = (6 + 18)/2, (-2 + 8)/2
  • midpoint = (12,3)

thus, Pierre is wrong as their calculation failed to match the actual y-co-ordinate of the midpoint of AB .
