Reflections Algebraic

Find K' if the figure is reflected across the x-axis

• (4, 1))

• (-1, -4)

• (1, -4)

• (1, 4)

What is the Algebraic Notation for this Reflection?

• (x, y) → (y, x)

• (x, y) → (-x, y)

• (x, y) → (-y, -x)

• (x, y) → (x, -y)

State the line of reflection.

• Reflection across y-axis

• Reflection across x-axis

• Reflection across x = 1

• Reflection across y = 1

Reflect Point C over the y-axis:

• (-3, 2)

• (3,2)

• (-2,3)

• (3,0)

Which transformation is shown?

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

• 90^o clockwise rotation

• 90^o counter clockwise rotation

• Reflection across the y-axis

What is the algebraic representation when you reflect on the x axis?

• x,y -> x,-y

• x,y -> -x,y

What is the algebraic representation for reflecting a figure over the x-axis?

• (x, y) --> (x, -y)

• (x, y) --> (-x, -y)

• (x, y) --> (-x, y)

• (x, y) --> (y, -x)
