10 maj 2019 · What is the rule for a reflection across the X axis? The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P’, the coordinates of P’ are (5,-4).
15 cze 2022 · By examining the coordinates of the reflected image, you can determine the line of reflection. The most common lines of reflection are the \ (x\)-axis, the \ (y\)-axis, or the lines \ (y=x\) or\ (y=−x\). Figure \ (\PageIndex {2}\) The preimage above has been reflected across the \ (y\)-axis.
21 sty 2020 · Reflection Across Y=-X. When reflecting over the line y=-x, we switch our x and y, and make both negative.
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). 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.
21 lis 2023 · Using the rule for reflecting a figure across the x axis, convert each of the coordinates to their reflection. The rule for this type of reflection is ( a , b ) reflects to ( a , -b ).
A vertical reflection reflects a graph vertically across the x x -axis, while a horizontal reflection reflects a graph horizontally across the y y -axis. The reflections are shown in Figure 9. Vertical and horizontal reflections of a function.
