Find the vector and cartesian equation of a line passes through the points `(1,3,2)` and origin.

Explanation

To find the vector and Cartesian equations of the line passing through the points \( (1, 3, 2) \) and the origin \( (0, 0, 0) \), we can follow these steps:

### Step 1: Identify the points
We have two points:
- Point A: \( (1, 3, 2) \)
- Point O (the origin): \( (0, 0, 0) \)

### Step 2: Determine the direction vector
