Question

1. practice: organizing information and summarizing fill in the blanks to complete the list. midpoint of diagonal segment x - coordinate = average of y - coordinates of endpoints - - - coordinate = average of - - - coordinates of endpoints 10) practice: using visual cues fill in the blanks to explain the midpoint formula.

Explanation:

Step1: Recall mid - point formula concept

The mid - point of a line segment with endpoints \((x_1,y_1)\) and \((x_2,y_2)\) has coordinates that are the averages of the corresponding coordinates of the endpoints.

Step2: Identify the missing words

The x - coordinate of the mid - point of a line segment is the average of the x - coordinates of the endpoints, and the y - coordinate of the mid - point of a line segment is the average of the y - coordinates of the endpoints.

Answer:

y; x
