Answer 1

The coordinate of the midpoint of the segment is given by the average of the coordinates of the endpoints.

Midpoint = (Endpoint1 + Endpoint2)/2

Midpoint = (-9 + 6)/2

Midpoint = -3/2

Therefore, the coordinate of the midpoint of the segment is -1.5.

Answer 2

What are the coordinates of the midpoint of HX given that H(-1, 3) and X(7, -1)?
