1. The document discusses coordinate planes and identifying points using ordered pairs. It provides examples of ordered pairs and asks the reader to identify other coordinates. 2. It then discusses a vertical line l that passes through the point (3,7) and asks the reader to find 6 points on the line and 6 points not on the line, as well as how to tell if a point is on the line based on its coordinates. 3. Finally, it introduces transformations on coordinate planes and asks the reader questions about finding points with specific x- and y-coordinates or where the y-coordinate is less than the x-coordinate. It provides homework problems for further practice.
