Answer:

A. Count by hand.

B. Divide 20 by 2.

Explanation:

The midpoint between two points is found by the mean of their coordinates.

Endpoints at (0,0) and (20,0)

So we have x coordinates of 0 and 20. Their mean is:


(20 - 0)/(2) = 10

So we can find both counting by hand, or dividing 20 by 2.
