A square has sides of 6 inches and is dilated to form a square that has sides of 24. What is the scale factor?
1/4 because 6/24 = 1/4
4 because 24/6 = 4
30 because 24 + 6 = 30
No way to know with this information.

x - 3
x + 3
y - 3
y + 3
Which two transformations preserve orientation?

Which of the following could be a dilation?
(6x, 6y)
(x + 1, y - 5)
(x, -y)
(-x, -y)
Which of the following could be a translation?
(x + 5, y - 2)
(6x, 6y)
(-x, -y)
(0.5x, 0.5y)
How do you find the scale factor when given a dilation?
SF = new/original
SF = new + original
