Transformation Quick Check

The coordinate grid shows a pentagon. The pentagon is translated 1 unit to the left and 10 units down to create a new pentagon.

Which rule describes this transformation?

• (x, y) ----- (x - 1, y - 10)

• (x, y) ----- (x + 1, y - 10)

• (x, y) ----- (x - 1, y + 10)

• (x, y) ----- (x + 1, y + 10)

The coordinates of the vertices of a quadrilateral are P(1, 2), R(1, 4), S(3, 4), and T(4, 2).

Quadrilateral PRST is reflected across the y-axis to create quadrilateral P'R'S'T'

• (x, y) ------ (x, -y)

• (x, y) ------ (-x, y)

• (x, y) ------ (y, -x)

• (x, y) ------ (-y, x)
