Q. Lesson 3.8Give the reflection of the point29. (2,−5),y-axis
Reflecting Point Across Y-Axis: To find the reflection of a point across the y-axis, change the sign of the x-coordinate while keeping the y-coordinate the same.
Original Point (2,−5): The original point is (2,−5). Changing the sign of the x-coordinate gives us (−2,−5).
Check Reflection: Check the result to make sure the reflection is correct. The point (−2,−5) is indeed directly opposite to (2,−5) across the y-axis.
