The midpoint of a line segment is the point that is exactly halfway between the two endpoints. To find the midpoint of the line segment joining points A(2,-7) and B(2,3), we can use the midpoint formula:
Midpoint = [(x1 + x2) / 2, (y1 + y2) / 2]
where (x1, y1) and (x2, y2) are the coordinates of the two endpoints.
Substituting the values for A and B, we get:
Midpoint = [(2 + 2) / 2, (-7 + 3) / 2]
Midpoint = [4 / 2, -4 / 2]
Midpoint = [2, -2]
Therefore, the midpoint of the line segment joining points A and B is (2, -2).
