Math Problem Statement
Solution
The task involves reflecting points across the x-axis and y-axis based on the given points in Figures 1 and 2.
Reflection Instructions:
-
X-Axis Reflection:
-
A reflection over the x-axis changes the y-coordinate of a point to its opposite (multiply by -1), while the x-coordinate remains unchanged.
-
In Figure 1, there is a red point at coordinates (-4, 3). The x-axis reflection of this point will change the y-coordinate from 3 to -3, keeping the x-coordinate the same:
- Reflection: (-4, -3).
-
-
Y-Axis Reflection:
-
A reflection over the y-axis changes the x-coordinate of a point to its opposite (multiply by -1), while the y-coordinate remains unchanged.
-
In Figure 2, there is a red point at coordinates (-4, 3). The y-axis reflection will change the x-coordinate from -4 to 4, keeping the y-coordinate the same:
- Reflection: (4, 3).
-
Summary:
- X-axis reflection of (-4, 3) (from Figure 1) is (-4, -3).
- Y-axis reflection of (-4, 3) (from Figure 2) is (4, 3).
Would you like further clarification, or help plotting the reflected points?
Relative Questions:
- How would you reflect a point across the origin?
- What would be the reflection of a point across the line ?
- How does the reflection across the x-axis affect the quadrant in which the point lies?
- If you reflect a point over both axes, what is the transformation?
- Can a point remain unchanged after a reflection? Under what circumstances?
Tip:
Always remember: in reflections, only one coordinate changes sign depending on the axis you reflect over (x-axis for y, y-axis for x).
