Find the point which divides the line segment joining the points $(7,\ –6)$ and $(3,\ 4)$ in ratio 1 : 2 internally.

Given: A point which divides the line segment joining the points $(7,\ –6)$ and $(3,\ 4)$ in ratio $1 : 2$ internally.

To do: To find the point.

Solution:

Here $x_1=7,\ y_1=-6,\ x_2=3,\ y_2=4,\ m=1$ and $n=2$.

Using the division formula,

$( x,\ y)=( \frac{mx_2+nx_1}{m+n},\ \frac{my_2+ny_1}{m+n})$

$( x,\ y)=( \frac{1\times3+2\times7}{1+2},\ \frac{1\times4+2\times-6}{1+2})$

$( x,\ y)=( \frac{17}{3},\ \frac{-8}{3})$

Thus, $( \frac{17}{3},\ \frac{-8}{3})$ divides the line segment joining the points $(7,\ –6)$ and $(3,\ 4)$ in ratio $1 : 2$ internally.
