Answer:
The point C(x, y) after the reflection of the point (x,y) across the y-axis will become:
C(x, y) → C'(-x, y)
Explanation:
We know that the reflection of the point (x,y) across the y-axis is
the point (-x,y).
In other words, when a shape or object is reflected across the y-axis, the y-coordinate remains the same, but the sign of x becomes the opposite.
For example,
The point C(x, y) after the reflection of the point (x,y) across the y-axis will become:
C(x, y) → C'(-x, y)
If let suppose the coordinates of the original point C(1, 2), then after the reflection of the point C(1, 2) across the y-axis, the new coordinates of C would be transformed such as:
C(1, 2) → C'(-1, 2)
