Transformation of Shapes

Victor drew a square with vertices at (1, 2), (3, 2), (3, 4), and (1, 4). He slides the square 5 units up to create an image. What are the vertices of the image and the algebraic rule that describes this transformation?

• (6, 2), (8, 2), (8, 4), and (6, 4); (x + 5, y)

• (1, 7), (3, 7), (3, 9), and (1, 9); (x, y + 5)

• (1, –3), (3, –3), (3, –1), and (1, –1); (x, y – 5)

• (1, –2), (3, –2), (3, –4), and (1, –4); (x, –y)
