Example Question #1 : Midpoint Formula
A line segment has endpoints (0,4) and (5,6). What are the coordinates of the midpoint?
(0,6)
(2.5,-5)
(3,9)
(2.5,5)
(0,4)
(2.5,5)
A line segment has endpoints (0,4) and (5,6). To find the midpoint, use the midpoint formula:
X: (x1+x2)/2 = (0+5)/2 = 2.5
Y: (y1+y2)/2 = (4+6)/2 = 5
The coordinates of the midpoint are (2.5,5).
Example Question #81 : Coordinate Geometry
Find the midpoint between (-3,7) and (5,-9)
(4,-8)
(1,-1)
(1,-8)
(4,-1)
(-1,-1)
(1,-1)
You can find the midpoint of each coordinate by averaging them. In other words, add the two x coordinates together and divide by 2 and add the two y coordinates together and divide by 2.
x-midpoint = (-3 + 5)/2 = 2/2 = 1
y-midpoint = (7 + -9)/2 = -2/2 = -1
(1,-1)
Example Question #1 : How To Find The Midpoint Of A Line Segment
Find the coordinates for the midpoint of the line segment that spans from (1, 1) to (11, 11).
(5, 5)
(6, 5)
(7, 7)
(6, 6)
(5, 6)
(6, 6)
The correct answer is (6, 6). The midpoint formula is ((x1 + x2)/2),((y1 + y2)/2) So 1 + 11 = 12, and 12/2 = 6 for both the x and y coordinates.
Example Question #1 : How To Find The Midpoint Of A Line Segment
What is the midpoint between the points (–1, 2) and (3, –6)?
(1,2)
(3,1)
(1,–2)
(–1,2)
(–2,–1)
(1,–2)
midpoint = ((x1 + x2)/2, (y1 + y2)/2)
= ((–1 + 3)/2, (2 – 6)/2)
= (2/2, –4/2)
= (1,–2)
Example Question #1 : Midpoint Formula
A line segment connects the points and . What is the midpoint of this segment?
To solve this problem you will need to use the midpoint formula:
Plug in the given values for the endpoints of the segment: and .
Example Question #2 : Midpoint Formula
What is the midpoint between and ?
The midpoint is the point halfway between the two endpoints, so sum up the coordinates and divide by 2:
Example Question #2 : How To Find The Midpoint Of A Line Segment
has endpoints and .
What is the midpoint of ?
The midpoint is simply the point halfway between the x-coordinates and halfway between the y-coordinates:
Sum the x-coordinates and divide by 2:
Sum the y-coordinates and divide by 2:
Therefore the midpoint is (5.5, 6.5).
