Y=x reflection rule
Y=x reflection rule-The rule for a reflection in the line y = x is ( x , y ) → ( y , x ) Reflection in the line y = − x A reflection of a point over the line y = − x is shownRule Let y = f (x) be a function In the above function, if we want to do reflection through the yaxis, x has to be replaced by x and we get the new function y = f (x) The graph of y = f (x) can be obtained by reflecting the graph of y = f (x) through the y

A point reflection is just a type of reflection In standard reflections, we reflect over a line, like the yaxis or the xaxisFor a point reflection, we actually reflect over a specific point, usually that point is the origin $ \text{Formula} \\ r_{(origin)} \\ (a,b) \rightarrow ( \red a , \red b) $REFLECTION RULES Worksheet 17 REFLECTION OVER THE Y AXIS PREIMAGE LOCATION REFLECTION IMAGE LOCATION a) Place DEF on the coordinate grid atThe most common lines of reflection are the xaxis, the yaxis, or the lines y = x or y=−x The preimage has been reflected across he yaxis This means, all of the xcoordinates have been multiplied by 1 You can describe the reflection in words, or with the following notation ry−axis(x,y)→(−x,y) Notice that the notation tells you
