Answer:-
Given:
The point (4 , 2) divided the line segment joining the points (5 , 1) & (2 , y) in the ratio 1 : 2.
Using section formula ;
i.e., the point which divides the line segment joining the points in the ratio m : n is :
Let,
- = 5
- = 2
- = 1
- = y
- m = 1
- n = 2
Hence,
On comparing both sides we get,
4 = 12/3.
→ 4 = 4
And,
→ y = 4
Hence, the value of y is 4.
