Point R (-2,7) what is the reflection on x cordinate and y cordinate?

Answer 1

To find the reflection of the point R (-2, 7) across the x-axis and y-axis, you can use the following rules:

1. Reflection across the x-axis: For a point (x, y), the reflection across the x-axis is (x, -y).

   • For point R (-2, 7), the reflection across the x-axis is: \[ (-2, -7) \]

2. Reflection across the y-axis: For a point (x, y), the reflection across the y-axis is (-x, y).

   • For point R (-2, 7), the reflection across the y-axis is: \[ (2, 7) \]

So, the reflections of point R (-2, 7) are:

• Across the x-axis: (-2, -7)
• Across the y-axis: (2, 7)
