The given rule of translation represents a horizontal translation 3 units left.
(x,y) → (x - 3,y)
To perform the translation, we have to subtract 3 from each x-coordinate.
Reflection
To perform the reflection, we have to reflect the vertices of â–ł R'S'T' on the opposite side of y=-1 in a way such that the distance from the vertices to the line remains the same.
Final Glide Reflection
The final glide reflection is the combined translation and reflection.
