What is the ordered pair for C' if reflected over the y-axis?

• (-3, 2)

• (3, 2)

• (-2, 3)

• (3, 0)

A type of transformation where a figure is “flipped” over a line of symmetry. A reflection produces a mirror image of a figure.

• rotation

• translation

• dilation

• reflection

Reflect the image across x = -3

• I' (-1,-1) P' (-2,2) S' (-4,1) W' (-4,3)

• I' (-1,-1) P' (-2,-2) S' (-4,1) W' (-4,3)

• I' (-1,-1) P' (-2,-2) S' (-4,-1) W' (-4,3)

• I' (-1,-1) P' (-2,-2) S' (-4,1) W' (-4,-3)

Reflect the image across y = -x

• A' (1,-3) J' (-3,-4) T' (2,5) S' (-2,4)

• A (1,-3) J (3,-4) T (2,5) S (-2,4)
