Review on Transformations

Describe the transformation T(x,y) --> (x - 4, y +1) in words.

• Translate 4 units right and 1 unit down

• Translate 4 units left and 1 unit up

• Translate 4 units up and 1 unit left

• Translate 4 units down and 1 unit right

What is the pre-image of P'(3, 7) for the translation T< -2, 3 >?

• P(1, 10)

• P(6, 5)

• P(5, 4)

• P(0, 9)

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

• 90^o clockwise rotation about the origin

• 90^o counterclockwise rotation about the origin

• Reflection across the y-axis

• Reflection across the x-axis

Q(-5,2) is reflected over the y axis. Where is the new point located?

• Q'(5,2)

• Q'(-5,-2)

• Q'(-5,2)

• Q'(5,-2)

Point P(7,2) is translated up 2 units and left 5 units. Where is the new point located?

• P'(9,-3)

• P'(2,4)

• P'(2,0)

• P'(12,4)

Apply the following rule to the point A(-5,6):

T(x,y) --> (x - 3, y + 7)

• A'(3, 2)

• A'(-2, 1)

• A'(-8, 13)

• A'(-2, 13)

Where is A' located after T< 3, -2 >?

• A'(-1, 3)

• A'(5, 3)

• A'(5, 8)

• A'(3, 5)

If you were to rotate ABCD 180° about the origin, what would the coordinate of A' be?

• A'(-5, 5)

• A'(-3, -5)

• A'(-5, 3)

• A'(-3, 3)

The point that is to be transformed is called the:

• Pre-Image
• Image
• Post-Image
• Transformation

After being transformed the new point is called a(n):

• Pre-Image
• Post Image
• Transformed
