Math Transformations

Apply the following rule to the point (-5,6):
(x,y)-->(y,-x)

• (-5,-6)

• (5,-6)

• (6,5)

• (-6,5)

Choose the correct scale factor:

• 2

• 3

• 1/3

• 1/2

Algebraic Representation (Rule): (x,y) --> (x,-y)

• translates a figure down

• rotates a figure 90 degrees counterclockwise

• reflects a figure over the y axis

• reflects a figure over the x axis

Which of the following is the algebraic representation for a dilation?

• (x, y) → (x, 3y)

• (x, y) → (3x, 3y)

• (x, y) → (x, y - 3)

• (x, y) → (.5x, .4y)

B(-2, -4)
Reflect over the line y = x

• (2, -4)

• (-4, 2)

• (-4, -2)

• (4, 2)

What is the sequence of transformations?

• Reflect over the y then reflect over the x

• Reflect over the x then reflect over the y

• Translate 4 units then rotate 90˚

• Rotate 90˚ then reflect over the x
