Axis & Coordinates

In this video, Lucy introduces the basics of graphs, focusing on axes, coordinates, and quadrants. She explains the x and y axes, the concept of the origin, and how to read and write coordinates. The video also covers the practical applications of coordinates in maps, GPS, and computer graphics. Finally, it explains the division of graphs into quadrants and their numbering system.
