What is the 2x2 matrix that is a reflection across the line y= 2x? For example, when point P with coordinates (5,4) is reflecting across the Y axis and mapped onto point P', the coordinates of P' are (5,4)Notice that the ycoordinate for both points did not change, but the value of the xcoordinate changed from 5 to 5 You can think of reflections as a flip over a designated line of reflectionThis lesson is presented by Glyn CaddellFor more lessons, quizzes and practice tests visit http//caddellpreponlinecomFollow Glyn on twitter http//twitter

Reflection over Y = X When a point is reflected across the line y = x, the xcoordinates and ycoordinates change their place Similarly, when a point is reflected across the line y = x, the xcoordinates and ycoordinates change their place and are negated Therefore, The reflection of the point (x, y) across the line y = x is (y, x) TheReflection Translation of a quadrilateral across a line Notice that the lines extending from one point to its corresponding point are bisected by the line of reflection This means that to reflect a point, line, or object means to reconstruct it identical mirror image at exactly the same distance from the line/point of reflection Reflection can be found in two steps First translate (shift) everything down by b units, so the point becomes V=(x,yb) and the line becomes y=mxThen a vector inside the line is L=(1,m)Now calculate the reflection by the line through the origin,
