What is the 2x2 matrix that is a reflection across the line y= 2x? I know the matrix for the reflection across the line y = x in 2 Dimensions is $$ \begin{bmatrix} 0 & 1 \\ 1 & 0 \\ \end{bmatrix} $$ I am not sure how to find the matrix for the reflection in 3 DimensionsOr the columns in my identity matrix But a general theme is any of these transformations that literally just scale in either the x or y direction, and when I or, well, you could say, scale They can either shrink or expand in the x or y direction Or flip in the x or y direction, creating a reflection These are going to be diagonal matrices
Note that this matrix is symmetrical about the leading diagonal, unlike the rotation matrix, which is the sum of a symmetric and skew symmetric part Simple cases In order to check the above lets take the simple cases where the point is reflected in the various axis Reflection in yzExperts are tested by Chegg as specialists in their subject area We review their content and use your feedback to keep the quality high Previous question Next questionReflect over the xaxis When you reflect a point across the xaxis, the xcoordinate remains the same, but the ycoordinate is transformed into its opposite (its sign is changed) If you forget the rules for reflections when graphing, simply fold your paper along the xaxis (the line of reflection) to see where the new figure will be located Or you can measure how far your points are away

This video explains what the transformation matrix is to reflect in the line y=x This video explains what the transformation matrix is to reflect in the line y=x The formula for a line in two dimensions through the origin looks like this y = m x Using m (slope) in that formula, a reflection matrix looks like this R = 1 1 m 2 1 − m 2 2 m 2 m m 2 − 1 Check out this article for information on Householder transformation if you want to dive into the derivation of this formula Let T R 2 → R 2 be a linear transformation that maps the line y = x to the line y = − x Note that the linear transformation T is completely determined if the values of T on basis vectors of the vector space R 2 are known Let B = { 1 0, 1 1 }
