Question

What is the rule for the reflection ?

Answer 1

When you reflect, the y-coordinate remains the same, but the x-coordinate us transformed into the opposite (flip signs)

Answer 2

Notation Rule A notation rule has the following form ry−axisA → B = ry−axis(x,y) → (−x,y) and tells you that the image A has been reflected across the y-axis and the x-coordinates have been multiplied by -1. Reflection A reflection is an example of a transformation that flips each point of a shape over the same line.
