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

If (a, b) is reflected on the line y = x, its image is the point (b, a) If (a, b) is reflected on the line y = x, its image is the point (b, a) Geometry Reflection A reflection is an isometry, which means the original and image are congruent, that can be described as a "flip"The problem is asking us to reflect the point (8, 7) over the reflection line y = x We will follow the method described in the below videoThe reflection of any point (x, y) in the line y = x is given by (y, x) or the x and ycoordinate will be exchanged to each other Hence reflection of point ( 6 , 8 ) in the line x = y is ( 8 , 6 )

Vertical Reflection Apply a reflection over the line y=1 The procedure to determine the coordinate points of the image are the same as that of the previous example with minor differences that the change will be applied to the yvalue and the xvalue stays the same In the end, we would have A'(6,2), B'(5,7), and C'(5, 3)Yes, the answer is A x=0 Another way to say reflect across the yaxis is to say reflect across the line x=0 since the line created by graphing x=0 is the same as the yaxis An image that is a reflection across the yaxis, or across the line x=0, will have opposite xcoordinates from the preimage but identical ycoordinatesThe point (3,1) will reflect from below the xaxis over the mirror line and end up, above it, keeping the xcoordinate of 3 The ycoordinate needs some working out , how far is it from the mirror line?
