Transcribed Image Text:**Question:** What are the coordinates of each image?
**Text:**
1. \( R_{x\text{-axis}}(-5, 3) \)
2. \( R_{x\text{-axis}}(1, 6) \)
**Explanation:**
The given expressions represent points that have been reflected over the x-axis. In a reflection over the x-axis, the x-coordinate remains the same, but the y-coordinate is inverted (multiplied by -1). Therefore:
- The point \((-5, 3)\) would become \((-5, -3)\) after reflection.
- The point \((1, 6)\) would become \((1, -6)\) after reflection.
These transformations allow the visualization of how coordinates change with respect to reflections across the x-axis in a Cartesian plane.
