Question Analysis
The main focus is to understand how to use a negative scale factor to find the coordinates of a dilated point when the center of dilation is the origin.
Key Concept Explanation
- Dilation with a scale factor centered at the origin: For a point , the coordinates of the dilated point are given by . When is negative, it not only changes the size of the figure but also reflects the point across the origin.
