Of course there are other types of reflection transformations in $\mathbb{R}^2$ such as reflecting across the $x$axis, as well as the diagonal line $y = x$ The table below illustrates these transformations alongside their associated standard matrices It is good to verify where these standard matrices ariseReflection about the line y=x Once students understand the rules which they have to apply for reflection transformation, they can easily make reflection transformation of a figure For example, if we are going to make reflection transformation of the point (2,3) about xaxis, after transformation, the point would be (2,3) Here the rule we have applied is (x, y) >See the answer Show transcribed image text Expert Answer Previous question Next question Transcribed Image Text

How to do a reflection across the line y=x
How to do a reflection across the line y=x-When we want to create a reflection image we multiply the vertex matrix of our figure with what is called a reflection matrix The most common reflection matrices areRelative to this basis, the matrix of the reflection is simply Y = (1 0 0 0 1 0 0 0 − 1) from which you can get Υ via a change of basis B Y B − 1 Note that rightmultiplication by Y just changes the sign of the third column of a matrix

Then that line is drawn and its reflection across the line y = x is obtained The equation of the second line is determined, and key parameters for each line (namely, the slope, xintercept, and yintercept) are computed This information is used to make a general conjecture as to how the key parameters for one of the two lines are related to those for the other line All ofWe saw above the transformation matrix for reflection in the line y = x (which by definition goes through the origin at an angle of fortyfive degrees) It is somewhat trickier to find the transformation matrix for a point that must be reflected in a line which, although it goes through the origin, is defined by different values of x and y As an example, consider the line y = 2x, and aRotating the line back to it's original position;
