Find the point dividing the interval AB in the ratio if A(,) and B is (,)
To find the point that divides a segment into a particular ratio, determine the ratio by writing the numerator over the sum of the numerator and the denominator of the given ratio.
Next, find the rise and the run (slope) of the line. Finally, add times the run to the -coordinate of and add times the rise to the -coordinate of .
This process is summarized with the following formula:

P(,)=( , )
you have:

A(,) => ,
and
B is (,) => ,

(,)=( , )
(,)=( , )
(,)=( , )
(,)=( , )
(,)=( , )
