Plot the points and compute the slope of the line containing them.
`(-2,3),(2,1)`

Explanation

To solve the problem of plotting the points (-2, 3) and (2, 1) and computing the slope of the line containing them, we can follow these steps:

### Step 1: Identify the Points
The two points given are:
- Point A: (-2, 3) where x1 = -2 and y1 = 3
- Point B: (2, 1) where x2 = 2 and y2 = 1

### Step 2: Plot the Points
