When a point is reflected over y=x, the following change occurs ⇒ We are given the point (7,8) Essentially, we change the signs for both coordinates, then flip the xcoordinate and ycoordinate 1 Change the signs ⇒ 2 Flip the x and y coordinatesOne final common reflection we see a lot is the reflection of a figure over the line y = x Let's examine a different figure in order to see the effects of this reflection To the right we have triangle PQR with points (1, 1), (4, 1), and (1, 3), respectively10/5/19 · A reflection of a point, a line, or a figure in the X axis involved reflecting the image over the x axis to create a mirror image In this case, the x axis would be called the axis of reflection Math Definition Reflection Over the Y Axis A reflection of a point, a line, or a figure in the Y axis involved reflecting the image over the Y axis to create a mirror image
