Question

Find the ratio in which the points (5,-20)
divide the line segment joining
the points
(4,7) & (1,2)
​

Answer 1

Explanation:

point p X coordinates:-

mx2 + nx1÷ m+n

k×1 + 1×4÷k+1=k+4÷k+1

point p Y coordinate s:-

my2 + my2

k×7 + 1×2÷k +1=7k+2÷k+1

ATQ:-

k+4÷k+1,=5

k+4=5k+5

k-5k=5-4

-4k=1

k=-1÷4

ratio:- 1÷4:1
