5C: Reflections

Front

What are the coordinates of point K if it is reflected over the x-axis?

Back

If point K has coordinates (x, y), after reflection over the x-axis, the new coordinates will be (x, -y). For example, if K is (5, 2), after reflection, it will be (5, -2).

Front

Reflections over the x-axis change the ____-__________.

Back

y-coordinate.

Front

What is the effect of reflecting a point over the y-axis?

Back

The x-coordinate changes sign. For example, if point A is (3, 4), after reflection over the y-axis, it becomes (-3, 4).

Front

What is the result of reflecting a point with coordinates (a, b) over the x-axis?

Back

The new coordinates will be (a, -b).

Front

Which transformations are involved in creating an image on a graph?

Back

Transformations can include reflections, rotations, and translations.

Front

What axis is the image reflected over in the given question?

Back

X-axis.

Front

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

Back

The x-coordinate changes sign, while the y-coordinate remains the same.

Front

If a point (x, y) is reflected over the x-axis, what are the new coordinates?

Back

(x, -y).

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

Describe the transformation: Reflection over the x-axis followed by a translation 3 units up.

Back

First, reflect the point over the x-axis, then move it 3 units up.
