The coordinate point (3.5, 3.5), the reflection of the coordinate across the y-axis will form a pre image at (-3.5, 3.5)
Reflection of coordinates
If a coordinate (x,y) is reflected across the y-axis, the equivalent coordinate points will be given as (-x, y).
Using the translation for the reflections;
- [tex](x,y) \rightarrow (-x, y)[/tex]
Give the coordinate point (3.5, 3.5), the reflection of the coordinate across the y-axis will form a pre image at (-3.5, 3.5)
