The resulting orientation of the two figures are opposite Corresponding parts of the figures are the same distance from the line of reflection Ordered pair rules reflect over the xaxis (x, y), yaxis (x, y), line y = x (y, x) The following diagram shows how to reflectFor triangle ABC with coordinate points A (3,3), B (2,1), and C (6,2), apply a reflection over the line y=x By following the notation, we would swap the xvalue and the yvalue A (3,3), B (2,1), and C (6,2) would turn into A' (3,3), B' (1,2), and C' (2,6)Translated according to the rule (x, y) → (x 2, y 8) and reflected across the yaxis A triangle has vertices at B (−3, 0), C (2, −1), D (−1, 2) Which series of transformations would produce an image with vertices B″ (4, 1), C″ (−1, 0), D″ (2, 3)?

To write a rule for this reflection you would write rx−axis (x,y) → (x,−y) Notation Rule A notation rule has the following form ry−axisA → B = ry−axis (x,y) → (−x,y) and tells you that the image A has been reflected across the yaxis and the xcoordinates have been multiplied by 1Quiz & Worksheet Goals In these assessments, you'll be tested on The rules that govern reflections across both the x and y axes individually Identifying y=x reflections Identifying reflectionsQuestion Write a rule to describe each transformation 7) 10) 11) 12) ) ) Reflections Date Period Graph the image of the figure using the transformation given 1) reflection across y=2 2) reflection across the xaxis M w 3) reflection across y=x 4) reflection across y=1 5) reflection across x=3 6) reflection across y = x s

Reflection Across The YAxis With Rule by Lance Powell on To write a rule for this reflection you would write rx−axis(x,y) → (x,−y) Notation Rule A notation rule has the following form ry−axisA → B = ry−axis(x,y) → (−x,y) and tells you that the image A has been reflected across the yaxis and the xcoordinates have been multiplied by 1The point negative 8 comma 5 is reflected across the yaxis plot negative 8 comma 5 and its reflection across the yaxis so first let's plot negative 8 comma 5 so its xcoordinate is negative 8 so I'll just use this one right over here so the xcoordinate is negative 8 and the ycoordinate is 5 so I'll go up 5 so the ycoordinate is 5 right over here you see negative 8 and 5 we've gone 8 to

What point do you get if you reflect the point ( 6,1) over the line y = x?Let y = f (x) be a function In the above function, if we want to do reflection through the yaxis, x has to be replaced by x and we get the new function y = f (x) The graph of y = f (x) can be obtained by reflecting the graph of y = f (x) through the yaxisThe rule for a reflection over the x axis is ( x , y ) → ( x , − y ) Reflection in the y axis A reflection of a point over the y axis is shown

What is important to note is that the line of reflection is the perpendicular bisector between the preimage and the image Thus ensuring that a reflection is an isometry, as Math Bits Notebook rightly states Reflection on a Coordinate Plane Reflection Over X Axis When reflecting over (across) the xaxis, we keep x the same, but make y negative 👍 Correct answer to the question 6 Which transformation below would have a number as part of its algebraic rule?Write the coordinate notation rule in terms of x and y for reflection over the yaxis Unit 2, 93

Corresponding parts of the figures are the same distance from the line of reflection Ordered pair rules reflect over the xaxis (x, y), yaxis (x, y), line y = x (y, x) This video shows reflection over the xaxis, yaxis, x = 2, y = −2 Show Video Lesson This video shows reflection over y = x, y = − x A reflection that results inReflections and Rotations We can also reflect the graph of a function over the xaxis (y = 0), the yaxis(x = 0), or the line y = x Making the output negative reflects the graph over the xaxis, or the line y = 0 Here are the graphs of y = f (x) and y = f (x)Y=x reflection rule The general rule for a reflection in the y x If point on a shape is reflected in the line y x Now the rule for reflecting a point about the line y x is 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 Found a
