QUESTION 1
The point  C(3.6, -0.4) divides AB in the ratio 3 : 2.
The coordinates of A are (-6, 5).
Let the coordinates of B be 
We use the formula:
 to determine the x-coordinate of B.
 to determine the x-coordinate of B.
We substitute the known values to obtain:
 
 

 
 
 
 
This implies that:
 
We also use the formula:
 to find the y-coordinate.
 to find the y-coordinate.






The coordinates of B are (10,-4)
QUESTION 2.
If point D divides CD in the ratio 4 : 5.
Then the coordinates of D are:


The coordinates of D are
