When point $A(x_{1}, y_{1})$ and point $B(x_{2}, y_{2})$ are joined to form $\overline{AB}$ and a point divides $\overline{AB}$ in the ratio $\lambda : 1$,the coordinates of the point are:

  • A
    $\left(\frac{\lambda x_{2}+x_{1}}{\lambda-1}, \frac{\lambda y_{2}+y_{1}}{\lambda-1}\right)$
  • B
    $\left(\frac{\lambda x_{2}+x_{1}}{\lambda+1}, \frac{\lambda y_{2}+y_{1}}{\lambda+1}\right)$
  • C
    $\left(\frac{\lambda x_{1}+x_{2}}{\lambda-1}, \frac{\lambda y_{1}+y_{2}}{\lambda-1}\right)$
  • D
    $\left(\frac{\lambda x_{1}+x_{2}}{\lambda+1}, \frac{\lambda y_{1}+y_{2}}{\lambda+1}\right)$
