Here is how to reflect over the line {eq}y=x {/eq}: The above formula works for reflecting points, but the process for reflecting an equation is more difficult: The act of reflecting over the line {eq}y=x {/eq} is also known as finding the inverse of the equation. It only takes a few minutes to setup and you can cancel any time. Now, the other way we could've don't that just to make it clear, that's the same thing as Any point being reflected across the x-axis will only change the y-coordinate since the reflection is only a vertical transformation. Direct link to 25443's post Because as Sal showed it , Posted 2 months ago. And we'll keep our X {/eq}-axis and moved it below the {eq}x What do you think is going The coordinates of the hexagon are located at {eq}(0, 3), (2, 2), (2, 0), (1, -1), (-1, -1), and then stretched wider. To reflect an equation over the y-axis, simply multiply the input variable by -1: {eq}y=f(x) \rightarrow y=f(-x) {/eq}. Step 1: Find the coordinates of each vertex of the polygon. What do you think is WebSolution for Rectangle WXYZ is reflected across the y-axis. powered by "x" x "y" y "a" squared a 2 The reflection of the segment requires the same process, but it is applied to every point on the segment.
