11.1

2: What type of transformation is used to change the position of a graph?

3: Label the vector like a ray, and use <x, y> notation for its component form.

6: Plot the three points making △DEF, and then translate each point according to the translation vector given.

9: How does x change and how does y change to get from the original point P to its image P’?

11: Use mapping notation.

16: What point turns out to be (4, -3) after being transformed according the mapping given?

17: This is the same as #6, but with mapping notation.

27: Use the Pythagorean theorem to determine how far it travels, and then divide the rate by 24.5/24.5 to convert to millimeters per second (instead of millimeters per 24.5 seconds).

30: A translation only moves a graph; it does not change any lengths or other measures.

32: A translation only moves a graph; it does not change its shape.

33: The mapping from the image back to the pre-image is the reverse of the mapping of the pre-image onto the image.

43: The fold can be diagonal.

49: Subtracting a negative term is the same as adding a positive term.
