Plot B’, the reflection of B over the y-axis
To plot the reflection of a point B over the y-axis, you need to reflect it with respect to the y-axis, which means changing the sign of its x-coordinate while keeping the y-coordinate the same.
Suppose point B has coordinates (x, y). Its reflection over the y-axis, denoted as B', will have coordinates (-x, y).
Here's an example:
Assume that B is located at (3, 2), so it has coordinates (3, 2).
To reflect point B across the y-axis, we simply change the sign of the x-coordinate, resulting in B' at (-3, 2).
To visualize this, let's consider a simple plot:
```
^
|
| B (3,2)
| .
|
--------B'(-3,2)
| .
|
|
```
In this diagram:
- The vertical line represents the y-axis.
- Point B is located at (3, 2).
- Point B' is the reflection of point B over the y-axis and is located at (-3, 2).
If you need a more accurate graphical representation, you would typically use graphing software or a graphing calculator. In a text-based medium like this, a detailed plot is not possible, but hopefully, the description and simple ASCII art provide a conceptual visualization.
