what is the ordered pair for the reflection of point P (-2, -2.5) when it is reflected across the y-axis?

Answer 1

To reflect a point across the y-axis, you change the sign of the x-coordinate while keeping the y-coordinate the same.

For the point \( P(-2, -2.5) \):

• The x-coordinate is \(-2\), and its reflection will be \(2\).
• The y-coordinate remains \(-2.5\).

Thus, the reflection of point \( P \) across the y-axis is \( (2, -2.5) \).

The ordered pair for the reflection is \( (2, -2.5) \).
