Question

Part APredict what will happen to the coordinates of a point Xy) as the point reflects across a line to produce point (x,y). Choose the x-axis, y-axis, y = xand y = -x for the lines of reflection. Express your answers in terms of x and y. (Be sure to watch your signs.)

Answer 1

Reflection across the line y = x transforms the point (x,y) into (y,x)

Reflection across the line y = -x transforms the point (x,y) into (-y,-x)
