Answer:
The slope of PV is -4. i.e. 
Step-by-step explanation:
Considering the triangle PSV as shown on coordinate grid
From the coordinate grid, it is clear that:
- The coordinates of P vertex is (2, 4)
- The coordinates of V vertex is (3, 0)
The slope of PV can be used using the slope formula




Therefore, the slope of PV is -4. i.e.
