most complete. Point reflections, formula and examples explained with. First translate (shift) everything down by b units, so the point becomes v finally use the intersection point in midpoint formula to get the required point.

SOLUTION: If the graph of the line x-2y=-1 in the xy-plane ... from www.algebra.com

In this case, the figure is reflected across the y− axis. Before we get into reflections across the y axis, make sure you've refreshed your memory on how to do simple vertical translation and horizontal translation. Formula for point reflection over origin.

Find a formula for the reflection across the line y = x + 1.

First, let us start with all situations where you can just follow a rule to quickly find the location of the reflected image on the coordinate system. The following table describes some reflections across some other common planes: Additionally, symmetry is another form of a reflective transformation. Keep in mind that once you know how to find a reflection image for a point, you can easily find it for a shape.
