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?
A (6,2), (8, 2), (8, 4), and (6, 4); (x + 5, y)
B (1,7), (3, 7), (3, 9), and (1, 9); (x, y + 5)
C (1, -3), (3, -3), (3, -1), and (1, -1); (x, y - 5)
D (1,-2), (3,-2), (3, -4), and (1,-4); (x, -y)

Why a is wrong?

And why b is correct

Answer 1

B

Explanation:

The y coordinate tells us when we are going up for down. So the rule would be (x, y + 5) So, the x coordinate stays the same and the y goes up 5.

(1,2) The 2 is the y coordinate. It will increase by 5 and become (1,7)

(3,2) The 2 is the y coordinate. It will increase by 5 and become (3,7)

(3,4) The 4 is the y coordinate. It will increase by 5 and become (3,9)

(1,4) The 4 is the y coordinate. It will increase by 5 and become (1,9)
