Find the coordinates of the midpoint of the segment whose endpoints are H(10, 1) and K(4, 7).
Oliga [24]

The formula of a midpoint of a segment AB:

A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)

We have:

H(10; 1); K(4; 7)

substitute:

M_{HK}\left(\dfrac{10+4}{2};\ \dfrac{1+7}{2}\right)\to M_{HK}\left(\dfrac{14}{2};\ \dfrac{8}{2}\right)\to M_{HK}(7;\ 4)

Answer: (7, 4)
