Graphing Dilations Using Coordinates

This lesson teaches how to graph images after dilation using coordinates. It explains the concept of scale factor, showing how a factor greater than 1 enlarges an image, while a factor between 0 and 1 reduces it. The lesson includes examples of graphing dilations with scale factors of 2 and 3, and a reduction with a scale factor of 1/2. Each example demonstrates the proportionality of dilated figures and emphasizes that the resulting image is similar but not congruent to the pre-image.
