Rotate a figure 90 degrees counter clockwise about the origin

The video tutorial explains how to rotate a figure 90 degrees counterclockwise about the origin, which is equivalent to a 270-degree clockwise rotation. It introduces two methods: using paper to visualize the rotation and applying a coordinate transformation rule. The rule involves swapping the x and y coordinates and negating the new x coordinate. The tutorial demonstrates how to graph the new coordinates and compare them to the original graph.
