2.4 Assignment

Determine where X' would be if you translated X 3 units to the left and 9 units down.

• (-4, 4)
• (-10, 2)
• (-4, -5)
• (-1, 5)

What transformation is happening?
(x, y) ----> (x + 2, y - 3) 

• slide up 2, left 3
• slide right 2, up 3
• slide right 2, down 3
• slide left 3, right 2

The original figure prior to a transformation.

• Pre-image
• Image

What rule describes the translation?

• (x - 6, y + 2)
• (x - 2, y + 6)
• (x + 2, y - 6)
• (x + 6, y - 2)

What axis is the triangle being reflected over?

• X-axis

• Y-axis

Which answer shows a reflection across the x-axis?

• d
• c
• b
• a

You want to reflect a figure over the horizontal line shown. 
What directions would you give? 
Reflect over the line: ________

• x = -4
• y = -4
• x - y = 4
• None of these

What is the rule for the following reflection? 

• Reflection across       y = 3
• Reflection across        x = −3
• Reflection across            x = 3
• Reflection across          y = −3

Which transformation is NOT a rigid motion (the size changes)?

• reflection
• rotation
• dilation
• translation

A rigid motion ...

• preserves size and location
• preserves shape and location
• preserves size and shape
• makes the figure larger
