What You Need To Know...
Find the lengths and midpoints of line segments in 2-D coordinate systems.
- The benchmark will be assessed using MC (Multiple Choice) and FR (Fill in Response) items.
- Items may include finding both distance and midpoint.
- Students may need to find the length or midpoint or one of the end points of a segment.
Example One
The circle shown below is centered as the origin and contains the point (-4, -2).
Which of the following is closest to the length of the diameter of the circle?
A. 13.41
B. 11.66
C. 8.94
D. 4.47
Example Two
On a coordinate grid, 
has an end point B at (24, 16). The midpoint of is P(4, -3). What is the y-coordinate of Point A.
