Answer from gabriel SHOW ANSWER After the reflection over the line y = x, the image of the point is (3,2) Stepbystep explanation When a given point is reflected over a line the point only changes place but the distance between the point and the line remains same Let (x,y) be a point on the plane andWhen the line of reflection is the line x = y, as in Figure 5, the equations for the reflection will be x = y', and y = x' These can be used the same way as before The image of (3,1) is (1,3), and the image of the ellipse x 2 4y 2 = 10 is 4x 2 y 2 = 10 (after dropping the Figure 4 Illustration by Hans &Ry−axis(x,y)→(−x,y) Notice that the notation tells you exactly how each (x,y) point changes as a result of the transformation Example A Find the image of the point (3, 2) that has undergone a reflection across a) the xaxis, b) the yaxis, c) the line y=x, and d) the line y=−x Write the notation to describe the reflection Solution 39
How do you find the image of a point in the XY plane?, So, it is clear that the image of point (5,2, 7) with respect to XY–plane is (5,2,7) Now we should find the image of point (4,0,7) with respect to line y=0 Now we should compare y=0 with axbycz=d Furthermore, Where is the image of a point that is on the line of reflection?, A reflection over line is a transformation in3 units up So the reflected point needs to be 3 units above the mirror line The ycoordinate of the mirror line is 2 so 3 up from that is 5Let T R 2 →R 2, be the matrix operator for reflection across the line L y = x a Find the standard matrix T by finding T(e1) and T(e2) b Find a nonzero vector x such that T(x) = x c Find a vector in the domain of T for which T(x,y) = (3,5) Homework Equations The Attempt at a Solution a I found T = 0 11 0
Use our online point reflection calculator to know the point reflection for the given coordinates This calculator helps you to find the point reflection A, for the given coordinates of A (x,y) Just select an axis from the dropdown and enter the coordinates, the point reflection calculator will show the result Point reflection, also called as an inversion in a point is defined as an isometryA ray of light is send along the line x 2y 8 = 0 After refracting across the line x y 1 = 0 it enters the opposite side after turning by 1 5 o away from the line x y 1 = 0, then the equation of the line along which the reflacted ray travel isThe image of the point (4,3) under a reflection across the line y =− x is (− 3, − 4) o True o False Justify your answer The image of the point (− 1, − 5) under a reflection across the y = x is (− 7, − 3) o True o False Justify your answer Point A (1,3) is reflected across the xaxis to create point A ' The line y = 2 x − 5

Line segments I end this segment i n over here and T oh this is T oh here are reflected over the line y is equal to negative X minus 2 so this is the line that they're reflected about this dashed purple line and it is indeed y equals negative X minus 2 this right over here is in slopeintercept form the slope should be negative 1 and we see that the slope of this purple line is indeed negative 1 if X changes by a certain amount and Y changes by the negative of that if X changes by 1 YSee Answer Check out a sample Q&A here Want to see this answer and more?Check all that apply The line of reflection, EH, is the perpendicular bisector of BB', AA', and CC' Nice work!

Answer Let's do it!Reflections What are the coordinates of the image of vertex G after a reflection across the line y=x?If the green line y=x were a mirror, the reflection of the point (8,3) would reflect like the dotted line shows That point is the INVERSE point (3,8) Notice that any time you reflect a point into the line y=x, you get the point with the x and y coordinates switched, called the INVERSE point You should find that interesting!
