Math Problem Statement

Identify and plot the point that is an x-axis reflection of the point in Figure 1. Identify and plot the point that is a y-axis reflection of the point in Figure 2.

Solution

The image you provided shows a pair of coordinate planes (Figure 1 and Figure 2) where the task is to identify and plot points that are reflections over the x-axis and y-axis.

Reflection Concepts:

  1. X-axis Reflection: A reflection across the x-axis changes the sign of the y-coordinate of a point. For example, a point (x,y)(x, y) reflected across the x-axis would become (x,y)(x, -y).

  2. Y-axis Reflection: A reflection across the y-axis changes the sign of the x-coordinate of a point. For example, a point (x,y)(x, y) reflected across the y-axis would become (x,y)(-x, y).

Analysis of the Image:

  • Figure 1 has a point plotted at approximately (2,3)(2, -3).
  • Figure 2 has a point plotted at approximately (4,4)(-4, 4).

Reflections:

  1. X-axis Reflection (for Figure 1):

    • Given Point: (2,3)(2, -3)
    • X-axis Reflection: The new point would be (2,3)(2, 3).
  2. Y-axis Reflection (for Figure 2):

    • Given Point: (4,4)(-4, 4)
    • Y-axis Reflection: The new point would be (4,4)(4, 4).

Would you like more details or explanations about this process? Here are some related questions:

  1. What would happen if you reflected a point across both the x-axis and the y-axis?
  2. How would the reflection differ if the point was on one of the axes?
  3. Can you explain how to reflect a point over the line y=xy = x?
  4. What is the result of reflecting the origin (0,0)(0, 0) over the x-axis and y-axis?
  5. How would you describe the transformation if the point was reflected over a different line, like y=xy = -x?

Tip: Always check the quadrant the original point is in before reflecting it, as this will help you anticipate where the reflected point should appear.
