If a point is reflected over the y-axis, the y-coordinate of the new point is equal to the original, while the x-coordinate is the negative of the original. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P’, the coordinates of P’ are (5,-4). The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. What is the rule for reflecting over the x axis? We can also reflect a figure in the coordinate plane in any point on the coordinate plane. When a figure is reflected over the line y=x, notice that the coordinates change order. When a figure is reflected over the y-axis, notice the x-coordinates change sign. What happens when a figure is reflected on a coordinate plane? Notice that the y-coordinate for both points did not change, but the value of the x-coordinate changed from 5 to -5. What are the coordinates of a reflection on the Y axis?įor example, when point P with coordinates (5,4) is reflecting across the Y axis and mapped onto point P’, the coordinates of P’ are (-5,4). It is also the starting, or zero, point for measuring how far a point is to the right or left (horizontally) on a graph. It shows you where an object on a Cartesian plane, a two-dimensional mathematical graph, is in the y (vertical) direction. What does the y-axis represent on a graph?
