Transformation Rules

The image of (2,5) after a reflection in the x-axis

The image ( -1,5) after T_-3,-2

A translation moves point A (4,-2) onto A' ( 0,2) what is the rule?

A rotation maps point A ( 7,9) onto point A' (-7,-9). What is the degree of rotation?

Pentagon R'S'T'U'V' is a transformation of RSTUV. Which rule describes this transformation?

• (x, y) --> (x, -y)

• (x, y) --> (-y, x)

• (x, y) --> (-x, -y)

• (x, y) --> (y, -x)

Reflections over the x-axis change the ____-__________. 

• y-coordinate

• x-coordinate

Write a rule for the translation.

•  (x - 1, y  + 2)

•  (x - 2, y  + 1)

•  (x + 2, y  - 1)

• (x + 1, y  -  2)

Match the following transformation rules.

• (x+4, y-3)

• Translation

• (2x, 2y)

• Reflection over the y-axis.

• Use the chart

• Reflection over the x-axis.

• (x, -y)

• Dilation

• (-x, y)

• Rotations

Write the Rule:

• Dilation 2.5

• Rotation 360°

• Reflection across the Y axis

• Dilation of .4

Write the Rule:

• Translation Left 2 Up 3

• Rotation 90° Counter Clockwise

• Rotation 180°

• Translation Right 2 Down 3
