Front

The point A (8, 12) was dilated to become point A' (2, 3). What was the scale factor?

Back

¼

Front

A dilation is which of the following: only an enlargement, only a reduction, either an enlargement or a reduction, neither an enlargement nor a reduction.

Back

Either an enlargement or a reduction

Front

Coordinate of the image of point B (4,9) under dilation with center at origin and scale factor of 2.

Back

B' (8 ,18)

Front

Coordinates of A(3, 6) under a dilation of 2?

Back

(6, 12)

Front

Dilate the figure by a scale factor of 3. What are the coordinates of the image? A(3,3) B(6,6) C(9,3)

Back

A'(9,9) B'(18,18) C'(27,9)

Front

The rule (x, y) --> (1/2x, 1/2y) will produce what type of image?

Back

Similar figure that is a reduction

Front

What scale factor was used to produce the image? Options: 2, -2, ¹/₂, 1

Back

¹/₂

Front

Dilate Point B by a scale factor of 1/2. Options: (1.5,-4), (-1.5,1), (-1,-1.5), (-2,-2)

Back

(-1.5,1)

Front

In a dilation, what mathematical operation is used with the scale factor? Options: addition, subtraction, multiplication, division

Back

multiplication

Front

When a dilation has a scale factor greater than one, the dilation is an enlargement.

Back
