The reflection of the point (6, -3) on the line $y = 2$ is:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (6, 7)
To find the reflection of the point $(6, -3)$ across the line $y = 2$, we can follow these geometric steps:
1. Identify the Type of Reflection
The line $y = 2$ is a horizontal line. When you reflect a point across a horizontal line:
- The $x$-coordinate remains exactly the same.
- The $y$-coordinate changes based on its distance from the line.
2. Calculate the Vertical Distance
The original point is at $y = -3$. The line of reflection is at $y = 2$.
- Distance from the point to the line $= |2 - (-3)| = 5$ units.
3. Determine the Reflected $y$-coordinate
Since the original point is 5 units below the line $(y=2)$, the reflected point must be 5 units above the line.
- New $y$-coordinate $= 2 + 5 = 7$.
4. Combine the Coordinates
- The $x$-coordinate stays $6$.
- The new $y$-coordinate is $7$.
- Reflected point: $(6, 7)$.
Conclusion
The reflection of the point $(6, -3)$ on the line $y = 2$ is $(6, 7)$.
