Answer 1

Answer:

The answer is simple as we do in 3 dimensional mathematics.

so, the coordinates of the point which divides the line is

(1,2,3)      A coordinate of segment is (-2,3,5)    B(7,0,-1)

Let the ratio be k:1

By section formula,

1 = k(7) + 1(-2)/ k+1

k+1 = 7k - 2

3 = 6k

k is 1/2

Ratio is 1:2
