A line segment on the coordinate plane has endpointsand. Which quadrant or axis contains its midpoint?
The-axis
Quadrant I
Quadrant IV
Quadrant II
第三象限
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.
