Chapter 6 Review: Transformations

If the figure is translated 3 units left and 4 units down, what are the coordinates of G' ?

• (-1, -3)

• (-3, -1)

• (-3, 1)

• (1, -3)

If the figure is rotated 90° clockwise about the origin, what are the coordinates of H' ?

*Rule: (y, -x)*

• (-3, 2)

• (3, -2)

After a transformation, the coordinates of J' are (0, -1). Which of the following best represents the transformation?

• a reflection over the y-axis

• a translation of 1 unit right and 2 units down

• a 90° clockwise rotation about the origin *The rule used is: (y, -x)*

• a dilation with a scale factor of 2

The ordered pair R(-2, 7) is translated 5 units to the right and down 2 units. Which of the following describes the translation using translation notation?

• (x - 5, y + 2)

• (x + 5, y - 2)
