Apr 9, 2025 · This free tutorial for students will teach you how to construct points and figures reflected over the x axis and reflected over the y axis. Together, we will work through several …

Reflections: Interactive Activity and examples. Reflect across x axis, y axis, y=x , y=-x and other lines.

Oct 24, 2025 · A reflection over the y axis is a fundamental coordinate transformation where each point (x, y) becomes (-x, y). This geometric transformation creates a mirror image across the …

Another transformation that can be applied to a function is a reflection over the x – or y -axis. A vertical reflection reflects a graph vertically across the x -axis, while a horizontal reflection …

Reflecting a figure over the y-axis can be a little tricky, unless you have a plan. In this tutorial, see how to use the graph of a figure to perform the reflection.

To reflect f (x) about the x-axis (that is, to flip it upside-down), use −f (x). To reflect f (x) about the y-axis (that is, to mirror it), use f (−x).

In a reflection about the y-axis, the y-coordinates stay the same while the x-coordinates take on their opposite sign. Algebraically, the ordered pair (x, y) becomes (-x, y).

May 16, 2025 · Learn how to reflect functions and points across the y-axis in Algebra I with clear examples, graphing tips, common mistakes, and practice problems.

On this lesson, you will learn how to perform reflections over the x-axis and reflections over the y-axis (also known as across the x-axis and across the y-axis) and reflections...

Reflect over the y-axis: When you reflect a point across the y -axis, the y- coordinate remains the same, but the x -coordinate is transformed into its opposite (its sign is changed).
