Question
The ratio in which the x-axis divides the line segment joining the points
(
6
,
4
)
and
(
1
,
−
7

Solution
Let the line segment joining the points (6,4) and (1,-7) be divided by the point on x-axis(x,0) in the ratio
k
:
1
.
Using section formula,
−
7
k
+
4
k
+
1
=
0
−
7
k
+
4
=
0
k
=

Therefore, the ratio
m
:
n
is
4
7
:

Hence,
m
+
n
=
