Answer:
The coordinates of the point
P
(
x
,
y
)
which divides the line segment joining the points
A
(
x
1
,
y
1
)
and
B
(
x
2
,
y
2
)
, internally, in the ratio
m

:
m

is given by the Section Formula.
P
(

What is Known?
The
x
and
y
co-ordinates of the line segment which is divided by the point
(
−
1
,
6
)
.
What is Unknown?
The ratio in which the line segment joining the points
(
−
3
,
10
)
and
(
6
,
−
8
)
is divided by
(
−
1
,
6
)
.
Steps:
From the figure,
Given,
Let the ratio in which the line segment joining
A
(
−
3
,
10
)
and
B
(
6
,
−
8
)
is divided by point
P
(
−
1
,
6
)
be
k
:
1
.
By Section formula
P
(
x
,
y
)
=
[
m
x

+
n
x

m
+
n
,
m
y

By Cross Multiplying & Transposing
k
=

Hence the point
P
divides
A
B
in the ratio
