Midpoint of a segment, whose two end points are
A
(
x
1
,
y
1
)
and
B
(
x
2
,
y
2
)
is
(
x
1
+
x
2
2
,
y
1
+
y
2
2
)
as
A
(
x
1
,
y
1
)
is
(
2
,
−
3
)
, we have
x
1
=
2
and
y
1
=
−
3
and a midpoint is
(
1
,
4
)
, we have
2
+
x
2
2
=
1
i.e.
2
+
x
2
=
2
or
x
2
=
0
−
3
+
y
2
2
=
4
i.e.
−
3
+
y
2
=
8
or
y
2
=
8
+
3
=
11
Hence coordinates of point
B
are
(
0
,
11
)
