Triangle ABC is going to be translated. How is ABC being translated if the rule (x,y) --> (x+3, y-2) is used?

• 3 up and 2 left
• 3 right and 2 down
• 3 left and 2 up
• 3 right and 2 up 

Which answer represents a reflection across the x-axis, using the algebraic rule (x,y) --> (x, -y)?

• d
• c
• b
• a

Identify the transformation from ABC to A'B'C'.

• 90^o clockwise rotation
• 90^o counter clockwise rotation
• Reflection across the y-axis
• Reflection across the x-axis

Identify the transformation from ABCD to A'B'C'D'.

• Translation
• Reflection across the x-axis
• Reflection across the y-axis
• 90^o counter clockwise rotation

When you translate
(x-2 , y + 6) the figure will move _____.

• 2 units right and 6 units right
• 2 units left and 6 units down
• 2 units left and 6 units up

How do you represent a translation Algebraically? 

• (-y, -x)
• (x + a, y + b)
• (-x , -y)
• (ax, by)

What does a translation do to an image?

• Turns it 90* clockwise
• Mirrors it
• Shrinks it
• Slides it

Which rule would result in a reflection in the x-axis?

• (x, y) → (2x, 2y)
• x, y) → (x + 4, y + 4)
• (x, y) → (y, -x)
• (x, y) → (x, -y)

What type of transformation is quadrilateral PQRS?
