<s>[INST] This is the solution to an exercise that provides a method for finding all pairs of reflection axes for two given points:

```python
import math

def distance(p1, p2):
    """Return the Euclidean distance between the two points."""
    return math.sqrt((p1[0] - p2[0])**2 + (p1[1] - p2[1])**2)

def slope(p1, p2):
    """Return the slope of the line joining the two points."""
    dx = p1[0] - p2[0]
    dy = p1[1] - p2[1]
    if dx == 0:
        return float('inf')[/INST]
