Answer:


Explanation:
To find the midpoint of the segment between two points located at (a, c) and (b, c), simply average the x-coordinates and the y-coordinates of these points:



Since the y-coordinates of points (a, c) and (b, c) are the same, they are located on the same horizontal line, y = c. Therefore, to find the distance between the two points, we only need take the absolute value of the difference of their x-coordinates:

Additional information
We take the absolute value of the difference between the x-coordinates when calculating the distance between two points with the same y-coordinate because it ensures that the distance is always positive. This measures the "length" of the line segment between the two points without considering direction.
