Using proportions, it is found that the coordinates of point C are given as follows: C(-7, -2).
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Point C divides the line segment OP into the ratio 3:5, hence the following equation is used to relate the points:

Then, for the x-coordinate:

x + 10 = 3
x = -7
For the y-coordinate:

y + 8 = 6
y = -2
The coordinates of point C are given as follows: C(-7, -2).
