Find the coordinates of the points of trisection of the line segment joining `(4,\ -1)` and ` (-2,\ -3)`.

Explanation

To find the coordinates of the points of trisection of the line segment joining the points \(A(4, -1)\) and \(B(-2, -3)\), we can follow these steps:

### Step 1: Understand the Concept of Trisection
Trisection means dividing the line segment into three equal parts. Therefore, we need to find two points \(P\) and \(Q\) such that \(AP = PQ = QB\).

### Step 2: Identify the Coordinates of Points
Let:
- \(A(x_1, y_1) = (4, -1)\)
