Answer:
0
Step-by-step explanation:
Given the points J (1,-10) and K (7, 2)
From the section formula

The y-coordinates of the point that divides the directed line segment from J to K into a ratio of 5:1 is obtained using the formula:

The y-coordinates of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.

the decimals are commas and the double decimal is a real decimal
(2y + 5)° = 4y °
- 4y + 2y° = -5°
-2y° = -5°
y =5/2
