Reflecting Points Across Axes

The video tutorial explains how to reflect points in the coordinate plane across the x-axis and y-axis. It covers plotting points A, B, C, and D, and demonstrates how to find their reflections by considering symmetry and quadrant changes. The tutorial emphasizes understanding the signs of coordinates in different quadrants and provides a step-by-step guide to reflecting points without using a graph.

What is the first step in reflecting a point across the x-axis?

• Move the point to the right

• Move the point to the left

• Change the x-coordinate to negative

• Ensure the point is symmetrical across the x-axis

After plotting point A at (1, 3), what are the coordinates of A' after reflecting across the x-axis?

• (3, 1)

• (-3, -1)

• (-1, 3)

• (1, -3)

What is the reflection of point B at (-2, -2) across the x-axis?

• (-2, 2)

• (2, -2)

• (-2, -2)

• (2, 2)

When reflecting point C at (-4, 5) across the x-axis, which quadrant does C' end up in?

• Quadrant I

• Quadrant II

• Quadrant IV

• Quadrant III

What are the coordinates of D' after reflecting point D at (2, -5) across the x-axis?

• (2, 5)

• (-5, -2)

• (-2, -5)

• (5, 2)

What changes when reflecting a point across the y-axis compared to the x-axis?

• The point moves left and right

• The x-coordinate becomes negative

• The point moves up and down

• The y-coordinate becomes positive

After reflecting point A at (1, 3) across the y-axis, what are the coordinates of A'?

• (-1, 3)

• (1, -3)

• (-3, 1)

• (3, -1)

What is the reflection of point B at (-2, -2) across the y-axis?

• (2, -2)

• (-2, -2)

• (-2, 2)

• (2, 2)

When reflecting point C at (-4, 5) across the y-axis, which quadrant does C' end up in?

• Quadrant IV

• Quadrant I

• Quadrant II

• Quadrant III

What are the coordinates of D' after reflecting point D at (2, -5) across the y-axis?

• (-2, -5)

• (2, 5)

• (-5, 2)

• (5, -2)
