Vocabulary
This is a transformation that results in a movement (slide) of a figure along a straight line.
What is translation?
The algebraic notation for a figure that is translated 3 units left.
What is (x-3, y)?

What is (-x,y)?

What is a rotation of 180 degrees?
A scale factor of 4/3 results in this type of dilation.

What is (x, y)-->(y, -x)
Given A(2, 1), these are the coordinates of A" after the following transformation: translated by (x-3, y+1), then reflected over the x-axis.
What is A"(-1, -2)?
This transformation turns a figure around a point.
What is rotation?

What is M'(1, 1)?
The line of reflection when A(-2, 0), B(1, 3), and C(3, -4) is reflected to A'(-2, 0), B'(1, -3), and C'(3, 4).
What is the x-axis?

What is rotation 270 degrees clockwise or 90 degrees counterclockwise?
These are the coordinates of Y' when X(12, 4), Y(8,2) and Z(-4,0) are dilated by a scale factor of 1/4.
What is Y'(2, 1/2)?
A transformation that moves each point along the ray through the point emanating from a fixed center, and multiplies distances from the center by a common scale factor.
What is a dilation?
