If AABC is reflected across the y-axis, what are the coordinates of C?

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)

Step-by-step 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)
