Definition

Vector Notation is used to describe how the x and y components of points translated change from preimage to image of the translation. Vector notation will always take on a few attributes as a part of the form. (x, y) → (x+ _____ , y+ _____)The blanks are where you would input how much each point on the preimage is changed by the translation.
