Let's determine the coordinates of the points on the coordinate plane.
- Point A: A is located at x = -1 and y = 0. Therefore, the coordinates of point A are (-1, 0).
- Point B: B is located at x = 2 and y = 1. Therefore, the coordinates of point B are (2, 1).
- Point C: C is located at x = -1 and y = -2. Therefore, the coordinates of point C are (-1, -2).
- Point D: D is located at x = 1 and y = -2. Therefore, the coordinates of point D are (1, -2).
Answer: A(-1, 0), B(2, 1), C(-1, -2), D(1, -2)
