Explanation of Translations
A Translation is a transformation that moves all points of a figure in the same direction and the same distance. Translations are created by using vectors, which have magnitude and direction. The vector on the graph has a magnitude of (-4, 2), or four units to the left and two units up. Each point on the preimage is translated by the vector to create the new image, four units to the left and two units higher than the preimage. Also, if a line were to be drawn connecting a point on the preimage and the same point on the image, then the line would be parallel to the vector.
