Exploring Coordinate Grids

The video tutorial covers the basics of coordinate grids, including the origin, x-axis, and y-axis. It explains how to plot points and write ordered pairs, emphasizing the importance of starting at the origin. The tutorial also demonstrates how to identify points inside a polygon, using a trapezoid as an example. Students are encouraged to take notes and practice plotting points to prepare for assignments and tests.
