Understanding Reflections in the y-axis | 8.G.A.3 💗💙

What happens to the coordinates of a point when it is reflected over the y-axis?

• The x-coordinate stays the same, and the y-coordinate changes to its opposite.

• The x-coordinate changes to its opposite, and the y-coordinate stays the same.

• Both the x and y-coordinates change to their opposites.

• The x and y-coordinates are swapped.

If point P has coordinates (3, -5) and is reflected over the y-axis, what will be the coordinates of its image, P'?

• (-3, 5)

• (3, 5)

• (-3, -5)

• (5, 3)

Consider a line segment with endpoints A(-4, 1) and B(-1, 4). If this line segment is reflected over the y-axis, what will be the x-coordinate of the reflected endpoint A'?

• -4

• 4

• 1

• -1

A point (x, y) is transformed into (-x, y). What type of transformation occurred?

• Reflection over the x-axis

• Reflection over the y-axis

• Rotation of 90 degrees

• Translation
