The document discusses the rectangular coordinate system, detailing how to determine the coordinates of points, plot them, and identify their quadrants. It includes examples of points in various quadrants and provides practice questions to reinforce the concepts. Key aspects include the definitions of x and y axes, quadrants, and ordered pairs.

2. 1. Determine the coordinates of a given point.
2. Plot points in the coordinate plane.
3. Determine the quadrant for a given
coordinate.
