None of the other answers
To find the midpoint, use the midpoint formula: . Plug in the two ordered pairs to the formula to get: . Doing this will give you a solution of .
Example Question #841 : Functions And Lines
A line segment on the coordinate plane has endpoints and . Which quadrant or axis contains its midpoint?
Quadrant IV
Quadrant II
The -axis
Quadrant III
Quadrant I
Quadrant II
The -coordinate of the midpoint is
,
which is negative.
The -coordinate of the midpoint is
,
which is positive.
Since the midpoint has a negative -coordinate and a positive -coordinate, the midpoint is in Quadrant II.
Example Question #11 : How To Find The Midpoint Of A Line Segment
A line segment on the coordinate plane has endpoints and . Which quadrant or axis contains its midpoint?
Quadrant IV
Quadrant III
Quadrant I
The -axis
Quadrant II
Quadrant I
The -coordinate of the midpoint is
,
which is positive.
The -coordinate of the midpoint is
,
which is positive.
Since both coordinates are positive, the midpoint is in Quadrant I.
