Which methods could you use to calculate the y-coordinate of the midpoint of a vertical line segment with endpoints at (0,0) and (0,15)?

a. count by hand
b. divide 15 by 2.
c. add the endpoint.
d. divide 1 by 15.

Option B.

Step-by-step explanation:

You need to remember that the y-coordinate of the midpoint is the average of the y-coordinate of the two points:

Given the endpoints (0,0) and (0,15) of the line segment, you can identify that the y-coordinate of each one are:

Then, when you substitute them into , you get:

Then, the method that you could use to calculate the y-coordinate of the midpoint of this vertical line segment is:

Divide 15 by 2.
