Scale Drawings on a Coordinate Plane

This video tutorial covers scale drawings on a coordinate plane, explaining key concepts such as scale drawing and scale factor. It guides students through plotting points on a coordinate plane, enlarging an image using a scale factor, and calculating new coordinates. The video concludes with a summary of key points and instructions for further tasks.

What is a scale drawing?

• A drawing that reflects the image over an axis

• A drawing that maintains the proportions of the original image

• A drawing that changes the size of a given image

• A drawing that alters the color scheme of the original image
