Based on the properties of a parallelogram, the slope of SR for PQRS to be a parallelogram would be: 2/3.
Given:
For PQRS to be a parallelogram, the slope of SR must be same as the slope of PQ.
This implies that: Slope of SR = Slope of PQ = 2/3.
Therefore, based on the properties of a parallelogram, the slope of SR for PQRS to be a parallelogram would be: 2/3.
