The correct Answer is:
To find the coordinates of B' when point B(3, 2) is reflected in the y-axis, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the coordinates of point B**: The coordinates of point B are given as (3, 2). 2. **Understand the reflection in the y-axis**: When a point is reflected in the y-axis, the y-coordinate remains the same, while the x-coordinate changes its sign. This means if the original point is (x, y), the reflected point will be (-x, y). 3. **Apply the reflection rule**: For point B(3, 2), we will change the sign of the x-coordinate. - The x-coordinate of B is 3, so the reflected x-coordinate will be -3. - The y-coordinate remains the same, which is 2. 4. **Write down the coordinates of B'**: Therefore, the coordinates of B' after reflection in the y-axis will be (-3, 2). ### Final Answer: The coordinates of B' are (-3, 2). ---
