1. **Problem Statement:**
Find the coordinates of point U given points Z(-4,0), G(-4,-6), and C on segment ZG such that C divides ZG in a certain ratio, and U lies on a line from C with given segment lengths.
2. **Given:**
- Z = (-4,0)
- G = (-4,-6)
- C lies between Z and G, with CG = 2.4 (distance from C to G)
- CU = 9 (distance from C to U)
3. **Step 1: Find coordinates of C.**
Since Z and G have the same x-coordinate (-4), segment ZG is vertical.
Length ZG = $|0 - (-6)| = 6$
C divides ZG such that CG = 2.4, so CZ = $6 - 2.4 = 3.6$
Using section formula for vertical segment:
$$y_C = y_Z - CZ = 0 - 3.6 = -3.6$$
Coordinates of C: $(-4, -3.6)$
4. **Step 2: Find coordinates of U.**
U lies on a line from C horizontally to the right (positive x direction), so $y_U = y_C = -3.6$
Distance CU = 9, so
$$x_U = x_C + 9 = -4 + 9 = 5$$
5. **Final answer:**
$$U = (5, -3.6)$$
This means point U is at coordinates (5, -3.6).
