The video tutorial explains how to graph points P, Q, R, and S on a plane using their position vectors. It then connects these points to form a quadrilateral and analyzes its properties to determine that it is a parallelogram. The tutorial verifies this by checking the slopes of opposite sides to confirm they are parallel.

What are the position vectors of points P, Q, R, and S?

• P: 2i + j, Q: -4i, R: -3i - 3j, S: 3i - 2j

• P: -2i - j, Q: 4i, R: 3i + 3j, S: -3i + 2j

• P: -2i + j, Q: 4i, R: 3i - 3j, S: -3i - 2j

• P: 2i - j, Q: -4i, R: -3i + 3j, S: 3i + 2j
