Graphs of Translations
A translation is a movement of a figure. When you perform a translation on a shape, the coordinates of that shape will change:
 translating ______ means you will add the translated unit to the coordinate of the points in the preimage
 translating ______ means you will subtract the translated unit from the coordinate of the points in the preimage
 translating ______ means you will add the translated unit to the coordinate of the points in the preimage
 translating ______ means you will subtract the translated unit from the coordinate of the points in the preimage
.
Translate the following figures:
 2 units down and 3 units right

1 unit up and 5 units left

4 units down and 1 unit left

Rules for Translations
A transformation is an operation that _____________, _____________, or _____________ a shape to create a new shape. There are two notations to write transformations:
 One notation looks like . This notation tells you to add 3 to the values and add 5 to the values.
 The second notation is a mapping rule of the form . This notation tells you that the and coordinates are translated to and .
Which notation is the most common? ____________________
.
A "rule for translation" is just a way of saying how the image was changed. It is the rule to follow if you want to recreate that image.
.
