So, the reflection of (4, 3) over the x-axis would be (-4, 3). The y-coordinate would remain unchanged (3 –> 3). To reflect this point over the x-axis, we would take the x-coordinate (4) and change its sign to negative (4 –> -4). Once the axis of reflection has been identified, all points and lines on one side of the axis must be reflected over to the other side.įor example, consider the point (4, 3). The x-axis is a horizontal line that runs from left to right, while the y-axis is a vertical line that runs from top to bottom. When reflecting points and lines in the coordinate plane, it is important to first identify the axis of reflection. How to Reflect Points and Lines in the Coordinate Plane Again, this results in a mirror image of the original. Similarly, when we reflect an image over the y-axis, we are flipping the image across a line that runs vertically through its center. This results in a mirror image of the original. When we reflect an image over the x-axis, we are essentially flipping the image across a line that runs horizontally through its center. For example, if a point had coordinates (3, 4), its new coordinates would be (3, -4). This means that all of the points in the figure will have coordinates that are opposites of their original coordinates. When we reflect a figure over the x-axis, we are essentially flipping the figure over a line parallel to the y-axis. In three dimensions, it can be used to find the equation of a plane given three points on that plane, or to find the points of intersection of a plane and a line. In two dimensions, it can be used to find the equation of a line given two points on that line, or to find the points of intersection of two lines. In mathematics, the rule of reflections is a method of solving certain types of problems by reflection. Reflections over the y-axis are called horizontal reflections. Reflections over the x-axis are called vertical reflections. There are two types of reflections: reflections over the x-axis and reflections over the y-axis. The point where the figure meets the axis of reflection is called the line of reflection. The line is called the axis of reflection. A reflection is a transformation that flips a figure over a line. In mathematics, reflections are a type of transformation. Reflection Over X Axis and Y Axis Introduction
