The harmonic conjugate of (4,-2) with respect to (2,-4) and (7,1) is?

Hii

The point has to be such that the distance between the points are in harmonic progression and assuming that we will get the answer.

Best of Luck

Let A(2,-4) and(7,1)The ratio in which (4,-2) divides AB2-4:4-7-2:-32:3 Therefore AB divides externally2(7)-3(2)÷2-3,2(1)-3(-4)÷2-314-6÷-1,2+12÷-1-8,-14.
