Question

1. practice: organizing information and summarizing

fill in the blanks to complete the list.
midpoint of horizontal segment
y - coordinate = average of x - coordinates of endpoints

• - coordinate = - - coordinates of endpoints

Explanation:

Step1: Recall mid - point formula concept

The mid - point of a line segment in a 2D - plane has its x - coordinate as the average of the x - coordinates of the endpoints and its y - coordinate as the average of the y - coordinates of the endpoints.

Step2: Fill in the blanks

The first blank should be "x", and the second blank should be "y".

Answer:

x; y
