What point do you get if you reflect the point ( 6,1) over the line y = x?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 yaxisThe rule for a reflection over the x axis is ( x , y ) → ( x , − y ) Reflection in the y axis A reflection of a point over the y axis is shown
