Reflections of Graphs

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)

How is triangle ABC being translated to triangle A'B'C'?

• up 3, left 8
• up 9, left 4
• down 3, right 8
• down 9, right 4

Write the rule for this translation:
Slide 3 up and 2 right

• (x, y)---->(x + 3, y + 2)
• (x, y)-----> (x+2, y + 3)
• (x, y)----> (x - 2, y + 3)

Which answer shows a reflection across the x-axis?

• d
• c
• b
• a

Reflecting over the y-axis changes the ____-_____________. 

• x-axis
• x-coordinate
• y-coordinate
• none of the above

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

• y-coordinate
• x-coordinate
• y-axis
• x-axis 

Identify the transformation.

• Reflection across y axis
• Reflection across x-axis
• 180 Rotation
• Translation 2 units down

Which rule would result in a translation of 2 units left and 3 units up?

• (x, y) → (2x, 3y)
• (x, y) → (x - 2, y + 3)
• (x, y) → (-x, -y)
• (x, y) → (x + 2, y - 3)

When translating a figure on a coordinate plane, which coordinate is affected by movement left and right?

• The x-coordinate
• The y-coordinate
• Neither

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)
