Answer: the two numbers are 6 and 10
Step-by-step explanation:
Given:
Consider the line segment YZ with endpoints Y(-3,-6) and Z(7,4).
To find:
The y-coordinate of the midpoint of line segment YZ.
Solution:
Midpoint formula:

The endpoints of the line segment YZ are Y(-3,-6) and Z(7,4). So, the midpoint of YZ is:



Therefore, the y-coordinate of the midpoint of line segment YZ is -1.
