Mariela drew the smaller triangle first. Then she dilated the image to produce a larger triangle. Which algebraic expression best describes the dilation?

• (x,y) --> (2.5x, 2.5y)

• (x,y) --> (x+3, y+3)

• (x,y) --> (5x, 5y)

• (x,y) --> (x+5, y+5)

In the following drawing, Triangle A'B'C' is the image of Triangle ABC after a clockwise rotation. What was the degree of rotation?

What are the coordinates of W'?

• (-1, -4)

• (1, 4)

• (-1, 4)

Determine where X' would be if you translated X 3 units to the left and 9 units down.

• (-4, 4)

• (-10, 2)

• (-4, -5)

Determine what happens to figure ABCD if it is dilated by a scale factor 2.

• Not enough information

• Stays the same size

• Enlargement - Gets bigger

• Reduction - Gets smaller

What happens to figure ABCD if it dilated by a scale factor between 0 and 1?

• Not enough information

• Size doesn't change

• Enlargement - Gets bigger

• Reduction - Gets smaller

Triangle ABC with vertices A (-2, 3), B(1, 0), C(5,-2) has been translated (x,y) --> (x-5, y+3). What are the coordinates of C'?
