Matrices and Reflections If you look at a white paper, you can see the light being scattered from it. Just add the transformation you want to to. If you reflect over the line y = -x, the x -coordinate and y -coordinate change places and are negated (the signs are changed). We can use matrices to translate our figure, if we want to translate the figure x+3 and y+2 we simply add 3 to each x-coordinate and 2 to each y-coordinate. Some of the common examples include the reflection of light, sound, and water waves. One of the primary transformations you can make with simple functions is to reflect the graph across the X-axis or another horizontal axis. When a figure reflects in a line or in a point, the image formed is congruent to the pre-image. Even if the function is complicated, you have to determine coordinates initially, divide the coordinate y-coordinate by (-1), and re-plot those coordinates. You may assume a point P = (x, y), which is the point whose reflection you want to find.
