Points A and B have co-ordinates (3, 4) and (0, 2) respectively. Find the image :
B" of B under reflection in the x-axis ".

Answer

To find the image of point B under reflection in the x-axis, we can follow these steps:

### Step 1: Identify the coordinates of point B
The coordinates of point B are given as (0, 2).

### Step 2: Understand the reflection in the x-axis
When a point (x, y) is reflected in the x-axis, the x-coordinate remains the same, while the y-coordinate changes its sign. Therefore, the reflection of point B will have the same x-coordinate but the opposite y-coordinate.

### Step 3: Apply the reflection rule
For point B with coordinates (0, 2):
- The x-coordinate remains the same: 0
- The y-coordinate changes sign: from 2 to -2

### Step 4: Write the coordinates of the reflected point
Thus, the coordinates of the image B" (B double dash) under reflection in the x-axis will be (0, -2).

### Final Answer
The image of point B under reflection in the x-axis is B" with coordinates (0, -2).
