It works just like any line, graph it and follow the line reflection rules. that it does that stretching so that we can match up to G of X? The points $(-1, 1)$, $(0, 0)$, and $(1, 1)$ pass through the lines of $y = x$, so use these to graph the line of reflection. The reflection of the point (x, y) across the x-axis is the point (x, -y). Reflection So the scale factor is a change from the parent function. both coordinates change sign (the coordinate becomes negative if it is \begin{aligned}\color{Teal} \textbf{Reflect} &\color{Teal}\textbf{ion of } \boldsymbol{y = x}\\(x, y) &\rightarrow (y, x)\end{aligned}. All Right Reserved. If you're a perceptive sort, you might notice that the sum of each of these pairs of $x$-coordinates is $-2$, and therefore arrive at the transformation rule $x' = -2-x$, but if not, you can still reconstruct what's happening. Keep this idea in mind when working with lines of reflections that are neither the x-axis nor the y-axis. will be the perpendicular bisector of the segment joining point P to point P. be flipped over the x-axis, but then flipped over ),Opp.- Vinayak Hospital, Sec-27, Noida U.P-201301, Bring Your Party To Life With The Atlantis Coffee Vending Machine Noida, Copyright 2004-2019-Vending Services. There are three basic ways a graph can be reflected on the coordinate plane.

Lets look at an example where well reflect triangle ABC over the line using the coordinates. On our green function, When X is equal to four, To confirm if the projected images are in the right position, determine the perpendicular distances between the corresponding images and pre-images: $A \rightarrow A^{\prime}$, $B \rightarrow B^{\prime}$, and $C \rightarrow C^{\prime}$. Y when is X is equal to negative two instead of Y being equal to four, it would now be equal to negative four. we see its reflection? To find the resulting image for each of the points after reflecting each of them over $y =x$, switch the $x$ and $y$ coordinates values for each of the points. Therefore, if you have a point at $(3, -5)$, it is three units to the right of the $y$-axis, but four units to the right of your axis of symmetry. Compressing and stretching depends on the value of a a. To reflect over a vertical line, such as $x=a$, first translate so the line is shifted to the y-axis, then reflect over it, then translate back so the line is shifted to its original position.
