Point c(3.6, -0.4) divides in the ratio 3 : 2. if the coordinates of a are (-6, 5), the coordinates of point b are . if point d divides in the ratio 4 : 5, the coordinates of point d are

Given:
A has coordinates (-6,5)
C has coordinates (3.6,-0.4).
C divides AB in the ratio 3:2.

Refer to the diagram shown below.
The coordinates of B are determined by

Also,


The coordinates of B are (10,-4).

Now, we know the coordinates of line segment AB as A (-6, 5) and B (10,-4).
D (x,y) divides AB in the ratio 4:5.
Therefore

Also,


The coordinates of D are (1.11, 1)
