Question

The point p(3,b)divides line A(1,2)and B(4,5)in ratio 2:1 from A,then find the value of b.

Answer 1

$\textbf{Answer :}$

Since, the point P divides the line joining the points A (1, 2) and
B (4, 5) into the ratio $\underline{2 : 1}$, then the co-ordinates of the P be

( (1×1 + 4×2)/(2+1), (2×1 + 5×2)/(2+1) )

$ i.e., ( (1 + 8)/3, (2 + 10)/3 ) $

$ i.e., ( 9/3, 12/3 ) $

$ i.e., (3, 4) $

By the given condition,

$ (3, b) $ Ξ $ (3, 4) $

Comparing both sides, we get

$\textbf{b = 4}$
