4.2 Re ections

Graph JKL and its image after a re! ection in the x-axis. 6. Graph JKL and its image after a re! ection in the y-axis. 7. Graph JKL and its image after a re! ection in the line y = x. 8. Graph JKL and its image after a re! ection in the line y = −x. 9. In Example 3, verify that FF— ′ is perpendicular to y = −x. Re! ecting in the Line y = x ................
