Question

A (15, 5), B (9, 20) and A-P-B. Find the ratio in which point P (11, 15)

divides segment AB​

Answer 1

Step-by-step explanation:

A(15,5) x1=15,y1=5

B(9,20)x2=9,y2=20

P(11,15)x=11,y=15

m:n=?

by section formula

x=mx2+nx1/m+n

11 =m(9)+n(15)/m+n

11 =9m+15n/m+n

11×m+n=9m+15n

11m+11n=9m+15n

11m-9m=15n-11n

2m=4n

m/n=4/2=2/1

Therefore,the required ratio is 2:1
