Transformations

Point A is located at (5,2).  Find the coordinates of A after a reflection over the x-axis.

• A’(5, -2)
• A’(-5, -2)
• A’(-5, -2)
• A'(5,2)

Describe the Transformation (x,y)→(x,y+4)

• translation right 4

• translation up 4

• translation left 1 and up 4

• translation right 1 and up 4

What transformation is happening?
(x, y) ----> (x + 2, y - 3) 

• slide up 2, left 3
• slide right 2, up 3
• slide right 2, down 3
• slide left 3, right 2

Point K (4, 2) is translated using this rule:
(x, y)----> (x + 3, y - 1) 
What are the coordinates of K'? 

• (6, 3)
• (7, 3) 
• (7, 1) 
• (5, 3) 

Pre-image: (3, 6)
Rule: (x,y) --> (x – 3, y + 4)
Coordinates of new image:

• (6, 2) 
• (0, 10) 
• (-3, 4) 
• (0, 2) 

Pre-image: (–3, 1)
Rule: Translate left 1 unit and up 2 units
Coordinates of new image:

• (–4, 3) 
• (–2, 3) 
• (1, 2) 
• (–4, -1) 

Pre-image: (5, –1)

Rule: Translate right 2 units and up 4 units

Coordinates of new image:

• (3, -5) 
• (7, –5) 
• (7, 3) 
• (2,4)
