Question

Which methods could you use to calculate the x-coordinate of the midpoint of a horizontal line segment with endpoints at (0, 0) and (20, 0)?

Answer 1

Add the two X coordinates

Divide by 2

Explanation:

Answer 2

You could add the two x-coordinates together (in this case, 0 and 20) and then divide them by 2 to get an x-coordinate of 10 for their midpoint.
