Question

1 point
8) The point which divides the line joining the points A(1,2) and B(-1,1)
internally in the ratio 1:2 in fraction​

Answer 1

Answer:

Let the given point C divide  A(1,2) and B(−1,1) internally in the ratio 1:2. 

Therefore, we have m=1 and n=2.

By section formula for internal division, the point C(x,y) is 

x=(m+n)(mx2+nx1) and y=(m+n)(my2+ny1)

x=(1+2)(−1×1+2×1) and y=(1+2)(1×1+2×2)

∴x=31 and y=35
