How do you write the algebraic notation when the scale factor is 3?
(x, y)→(1/3x, 1/3y)
(x, y)→(-3x, -3y)
(x, y)→(x + 3, y + 3)
(x, y)→(3x, 3y)
How do you write the algebraic notation when the scale factor is 1/2?
(x, y)→(2x, 2y)
(x, y)→ (1/2x, 1/2y)
(x, y)→(-2x, -2y)
(x, y)→ (2x, 1/2y)
(x, y) -> (2x, 2y)
What is the coefficient 2 mean?
plot 2 to the right and 2 up
scale factor is 2 creating a new figure half the size
scale factor is 2 making a figure twice the
original
flip it 2 times
Triangle ABC has vertices A (-2, 2), B (2, 4) and C (3, -1). What is the algebraic rule if it is dilated by a scale factor of 2.5?
(x, y)→(2.5x, 2.5y)
(x, y)→(x, 2.5y)
(x, y)→(x+2.5, y+2.5)
(x, y)→(x-2.5, 2y)
Rectangle ABCD is dilated by a scale factor of 3/2. What is the algebraic rule?
(2x, 3y)
(2/3 x, 2/3 y)
(3/2 x, 3/2 y)
(x + 2, y + 3)
Rectangle ABCD is dilated by a scale factor of 1.5
What is the rule?
(-2x, +1y)
(1.5x, 1.5y)
(x, 1.5y)
(x - 1.5, y - 1.5)
Figure S is dilated to create Figure T. What is the rule used to create the Figure T
(x, y)→(2x, 2y)

(x, y)→(1/3x, 1/3y)
(x, y)→(4x, 6y)
A figure was dilated to create a new figure, which rule represents an enlargement?
(x, y)→(.2x, .3y)
(x, y)→(x, -y)
(x, y)→(x+3, y+3)
(x, y)→(5x, 5y)
Which rule describes a reduction?
(x, y)→(-x, -y)
(x, y)→(1/5x, 1/5y)
(x, y)→(5x, 5y)
(x, y)→(1/4x, y+4)
Which rule describes a reduction?
(x, y)→(.33x, .33y)
(x, y)→(4x, 4y)
(x, y)→(x+.33, y+.33)
(x, y)→(x, -y)
