Question Analysis  

This question involves dilation, focusing on applying a scale factor of 2.1 with the origin as the center to find the image of point .  

Key Concept Explanation:  

Dilation from the origin scales coordinates by : . A scale factor k > 1 enlarges the figure.  

Step-by-Step Solution:  

For point :  

Multiply the -coordinate by 2.1: .  

Multiply the -coordinate by 2.1: .  

→ Image coordinates: .  

Common Mistakes  

Forgetting to scale both coordinates (e.g., only multiplying one coordinate).  

Incorrect decimal multiplication (e.g.,
