which methods could you use to calculate the y coordinate of the midpoint of a vertical line segment with end points at (0,0) (0, -12). check all that apply

Answer:
D
Step-by-step explanation:
I like count by hand. If all else fails (like not being able to enter -12 into your calculator), counting by hand is a time honored method of getting answers.
That is never the answer in a math class. You should answer dividing -12 by 2
