Midpoint on a Number Line
If the coordinates of the endpoints of a segment are given, then the coordinate of the midpoint of the segment is half the sum of the coordinates.
6
Examples: Use the number line to find the coordinate of the midpoint of each segment
Segment CE
CE = (-4 + 2)/2 = -2/2 = -1
Segment GA
GA = (8 + -9)/2 = -1/2 or -0.5
7
Midpoint Formula in a Coordinate Plane
The midpoint of two distinct points in a coordinate plane is obtained by taking half of the sums of the corresponding x- and y-coorndinates.

Midpoint Formula
Example 1:
Find the midpoint of the line segment with coordinates (-3, 3) and (5, 3).

Midpoint Formula
Example 2:
Given the coordinates (-4, 5) and (2, -3), what is the midpoint of the segment formed when the points are connected?
10
Midpoint Formula
Example 3:
Stella's location on the map is (1, 5) and Albert's location is (1, -1). They have decided to meet exactly halfway from each other. What are the coordinates of their meeting place?
