Unit 7 Transformations Test

The point that is to be transformed is called the:

• Pre-Image
• Image
• Post-Image
• Transformation

After being transformed the new point is called a(n):

• Pre-Image
• Post Image
• Transformed
• Image

What does a translation do to a figure on the coordinate plane?

• Rotates it
• Flips it
• Shrinks it
• Slides it

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)

Determine how to translate triangle A'B'C' to triangle ABC.

• (x+2, y-5)

• (x+2, y-9)

Triangle GHI is reflected across the x-axis.  What are the coordinates of I'?

• (-2, 6)
• (2, 6)
• (-6, -2)
• (6, 2)

What is the rule for the following reflection? 

• Reflection across       y = −1
• Reflection across        y = 1
• Reflection across            x = −1
• Reflection across          x = 1

If you reflect the point D ( 5, -1) over the y-axis, what is the reflected point?

• D' ( -5, -1)

• D' ( 5, -1)

• D' ( -5, 1)

• D' ( 5, 1)

Is the reflection shown a reflection over the x or y axis?

• x axis

• y axis

What is a reflection?

• When you turn an object around a point.

• When you slide an object form one place to another.

• When you flip or mirror an object across a line.

• When you resize an object.
