7th KAP Math Transformations Review

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

Which translation will move the blue shape to the green shape?

• 3 Left

  3 Down

• 3 Right

  3 Up

• 2 Right

  3 Up

• 2 Left

  3 Down

What does a translation do to an image?

• Turns it 90* clockwise
• Mirrors it
• Shrinks it
• Slides it

What does this transformation say to do?
(x, y) -----> (x, y +4) 

• slide down 4
• slide up 4
• slide right 4
• slide left 4

When translating left or right on a coordinate plane, what coordinate is affected?

• x-coordinate

• y-coordinate

When translating up or down on a coordinate plane, what coordinate is affected?

• x-coordinate

• y-coordinate

A transformation in which a graph or geometric figure is picked up and moved to another  location without any change in size or orientation.

• Translation
• Rotation
• Reflection
• Dilation

The result of a transformation.

• Pre-image
• Image

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)
