Question

the coordinates of the points P and Q are respectively (4,-3) and (-1,7)then the abscissa of a point R on the line segment PQ such that PR/PQ=3/5.

Answer 1

P============R==============Q
given ,
PR/PQ=3/5
PR/(PR+RQ)=3/5
5PR=3PR+3RQ
2PR=3RQ
PR/RQ=3/2
hence R divided the line segment PQ
is 3:2 ratio.
use section formula for x-axis
abssica of R={ 3 x (-1)+2 x 4} /5
=1
hence abssica of R is 1
