Find the coordinates of the midpoint of segment/hx large given that h(–1,3) and x(7,–1).

The coordinates of the midpoint of HX are (3, 1)

You can find the coordinates of any segment by taking the average of each respective part of the end point. 

When we take the average of the x values (-1 and 7) we get 3, and when we take the average of the y values (3 and -1) we get 1.
