Transformations

Find the incorrect statement

• the pre-image is located in quadrant IV

• rectangle wxyz was reflected across the x-axis

• the orientation of the figure was preserved

• the transformation can be represented as (x, y-8)

Quadrilateral PQRS has coordinates P(-5, -2), Q(-2, -2), R(-4, -6) and S(-7, -6). Where is P' after quadrilateral PQRS is reflected over the x-axis?

• (5, 2)

• (5, -2)

• (-2, 5)
