Question

if the point P(2,1) lies on the line segment joining A(4,2) and B(8,4) then AP=___AB (solve it clearly)​

Answer 1

Step-by-step explanation:

here is your answer and once try to solve it yourself

Answer 2

Answer:

A ==========P ==============B

A(4 , 2) B(8 , 4) and P (2,1)

use section formula ,

let PA : PB =m : n

then,

2 ={8 × m + 4 × n}/(m + n)

2(m + n) =(8m + 4n)

2m +2n =8m + 4n

-6m = 2n

m/n = 1 : -3

here negative sign means p externally divided of AB .
