(5,3)
(20,12)
(-20,-12)
(-5,-3)
(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
I don't understand this question : (
If the scale factor is greater than one, the new figure will be
reduction
enlargement
scale
not proportional
If the scale factor is less than one(typically a proper fraction), the new figure will be
an enlargement
a reduction
a scale factor
bigger

Reduction
Is this an enlargement or a reduction?
Enlargement
Reduction
Which of the following algebraic rules represents an enlargement?
(x, y) --> (3x, 3y)
(x, y) --> (0.5x, 0.5y)
(x, y) --> (0.75x, 0.75y)
(x, y) --> (0.999x, 0.999y)
(x, y) --> (5x, 5y)
Enlargement or reduction? Find the scale factor!
It's a reduction; the scale factor is 2.
It's an enlargement; the scale factor is 2.
It's an enlargement; the scale factor is 1/2.
It's a reduction; the scale factor is 1/2.
