Reflection across x axis

Reflection Across X Axis, How to Reflect a Graph Across an Axis Another type of graphing transformation is a reflection. Download over Reflect over the x-axis: When you reflect a point across the x -axis, the x- coordinate remains the same, but the y -coordinate is transformed into its opposite (its sign is changed). Enter coordinates, pick your line of reflection, and get the mirrored point instantly. • Reflected figures are congruent to the original. This lesson shows how the x-values stay the same while the y-values become opposites. Enter single coordinates, multiple lists, or a function rule. Reflect points and graphs across the x-axis. Home > Geometry > Coordinate Geometry > Distance between two points calculator Method and examples Method Reflection of a Point in x-axis, y-axis and origin Find Reflection of points A (0,0),B (2,2),C (0,4),D (-2,2) and Reflection about x-axis, y-axis and origin Reflection Across the x-axis: y = -f (x) This topic covers how to reflect the graph of a function across the x-axis using the rule y = -f (x). The reflection of a point about the x-axis is a new point where the x-coordinate stays the same and the y-coordinate changes its sign. If a point is (x, y), its reflection across the x-axis is (x, −y). A vertical reflection reflects a graph vertically across the x -axis, while a horizontal reflection reflects a graph horizontally across the y -axis.

If you forget the rules for reflections when graphing, simply fold your paper along the x -axis (the line of reflection) to see where the new figure will be located. See reflected values instantly below the heading. , that are on the top will be on the bottom after the transformation and if it is doing through the horizontal axis. Reflections are opposite isometries, something we will look below. Conceptually, a reflection is basically a 'flip' of a shape over the line of reflection. Need more transformation videos?

In reflection transformation, the size of the object does not change. • Reflections can be performed over the x-axis, y-axis, or any line. Download clean reports for lessons, checks, and assignments today. A vertical reflection reflects a graph vertically across the $x$ -axis, while a horizontal reflection reflects a graph horizontally across the $y$ -axis. • The line of reflection is equidistant from corresponding points on the figure and its image. When we talk about a reflection, it can be thought of as a folding or flipping of the graph over the line of reflection. • A reflection flips a figure over a mirror line. Jan 23, 2026 · Learn how to reflect points and shapes over the x-axis in the coordinate plane! 📐 In this video, we break down the geometry transformation rule (x, y) → (x, -y).
