Dear student
Let B divides A and C is ratio k:1
5k + 1/k+1 = 2
3k = 1
k = 1/3
Hence
Hence divides internally
Now harmonic conuugatc will be the point which divides A and C in 1:3 externally
Hence
Or we can say that A divides in 1:2 internally
2x + 5 / 3 = 1
x = -1
And
2y + 1/3 = -3
y = -5
Hence harmonic conjugate = (-1, -5)
