The mirror image of point (4, 3) about x-axis will bea)(4, -3)b)(-4, -...
Explanation:
To find the mirror image of a point about the x-axis, we need to reflect the given point across the x-axis. The x-coordinate of the point remains the same, but the y-coordinate changes its sign.
Given point: (4, 3)
To reflect this point across the x-axis, we keep the x-coordinate the same and change the sign of the y-coordinate.
The x-coordinate of the given point is 4. Therefore, the x-coordinate of the mirror image will also be 4.
The y-coordinate of the given point is 3. To find the y-coordinate of the mirror image, we change the sign of 3, which gives us -3.
Hence, the mirror image of the point (4, 3) about the x-axis is (4, -3).
Therefore, the correct answer is option 'A' (4, -3).

The mirror image of point (4, 3) about x-axis will bea)(4, -3)b)(-4, -...
Point A is 3 units above x-axis.
∴ Its mirror image will be 3 units below x-axis, and the x-coordinate will remain constant
∴ Coordinates of point B ≡ (4, -3)
