Reflections, Translations and Rotations

Which point shows a reflection of point      X(9, -2) over the x-axis?

• (-2, 9)
• (9, -2)
• (9, 2)
• (-9, -2)

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

Reflect Point C over the y-axis:

• (-3, 2)
• (3,2)
• (-2,3)
• (3,0)

• 4 units right
• 4 units left
• 4 units up
• 4 units down

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

• (2, -4)
• (-4, 2)
• (-4, -2)
• (4, 2)

Which represents translating right 4 and down 2?

• (x - 2, y + 4)

• (x - 4, y - 2)

• (x + 4, y + 2)

• (x + 4, y - 2)

Answer explanation

$\left(x,y\right)\longrightarrow\left(x+4,y-2\right)$

Translating right 4 means the x value increases by 4. Translating down 2 results in the y value decreasing by 2.

The original figure before a transformation.

• Pre-image

• Image

Answer explanation

The original figure is called the preimage because it is the image before a transformation (pre-transformation).
