Question

Find the coordinates of P so that P partitions the segment AB in the ratio 1:1 if

A(13,1) and B(−5,−3)?
.

Answer 1

P(4, - 1 )

Explanation:

The ratio 1 : 1 represents the midpoint of segment AB

Using the midpoint formula

[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]

with (x₁, y₁ ) = (13, 1) and (x₂, y₂ ) = (- 5, - 3), so

P = [0.5(13 - 5), 0.5(1 - 3) ] = [0.5(8), 0.5(- 2) ] = (4, - 1 )
