the line y = -x and then a translation along the vector
<-4, -4>.
$1000 Answer Transform It!
(2, -7)
$200 Question Know the Rules!
The rule for this transformation is (x, y) → (-x, y)
$200 Answer Know the Rules!
Reflection over y-axis
$400 Question Know the Rules!
The rule for this transformation is (x, y) → (y, -x)
$400 Answer Know the Rules!
90° clockwise rotation OR 270° counterclockwise rotation about the origin
$600 Question Know the Rules!
The rule for this transformation is (x, y) → (-y, -x)
$600 Answer Know the Rules!
Reflection over y = -x
$800 Question Know the Rules!
Write the rule you would use to find the image
coordinates of (x, y) under a translation of 2 units right
and 1 unit down.
$800 Answer Know the Rules!
The rule for this transformation is
(x, y) → (x + 2, y – 1)
$1000 Question Know the Rules!
Write the rule you would use to find the image coordinates of (x, y) under a dilation with scale factor = -1 followed by
180° rotation about the origin.
$1000 Answer Know the Rules!
The rule for this transformation is (x, y) → (x, y)
$200 Question Potpourri
Does the figure have line symmetry? If so, draw all lines of
symmetry.
$200 Answer Potpourri
Yes, 2 lines of symmetry.
$400 Question Potpourri
Does the figure have rotational symmetry? If so, give the angle of rotational symmetry and the order
of symmetry.
$400 Answer Potpourri
Yes, Angle of rotation = 72°,
Order = 5
$600 Question Potpourri
A translation can be interpreted as successive
reflections across two lines. Tell what relationship the lines must have for this to be true.
$600 Answer Potpourri
They must be parallel
$800 Question Potpourri
The pre-image is (10, -8), the image is
(2, -4). What is the translation vector?
$800 Answer Potpourri
<-8, 4>
$1000 Question Potpourri
What is the scale factor of a dilation centered at the origin that maps A(5, -6)
to A’(-15.5, 18.6)?
$1000 Answer Potpourri
k = -3.1
