You can put this solution on YOUR website! Line segment CD has endpoints (-3,8) and (1,-5). What are the coordinates of the point that divides CD in the ratio of 3:7?
-------
Ratio 3:7 --> 3/10 for x, 7/10 for y if it's closer to point C.
Find the x & y separately.
---
For x:
-3 to 1 --> +4 units
(3/10)*4 = 1.2
-3 + 1.2 = -1.8
====================
For y:
8 to -5 --> -13 units
(3/10)*-13 = -3.9
8 -3.9 = 4.1
=================
Point is (-1.8,4.1)
