To find the midpoint of line segment \( \overline{AB} \) on a coordinate plane, you would use the coordinates of points A and B. If you have the x-coordinates of points A and B, you can find the x-coordinate of the midpoint by adding these two x-values together and dividing by 2. The same procedure applies to the y-coordinates.
In the context of your question, if you are finding the midpoint using the operation \( 6 + 2 \) followed by dividing by \( 2 \), this represents finding the average of two numbers.
Assuming that \( 6 \) and \( 2 \) are the x-values of points A and B (or vice versa, depending on the context), the operation would yield the x-coordinate of the midpoint.
Thus, the correct answer would be:
It finds the average distance between the two x-values of points A and B.
