Question
Which of the following expression represents a dilation?
- (x, y)
(x + 3, y + 2) - (x, y) (x, 2y)
- (x, y) (3x, 3y)
- (x, y) (2x, y)
(x + 3, y + 2)(x, 2y)(3x, 3y)(2x, y)
Hint:
A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object.
Dilation is a process of changing the size of an object or shape by decreasing or increasing its dimensions by some scaling factors.
The correct answer is: (x, y) (3x, 3y)
Algebraic representation of dilation (x,y)(kx, ky), where k is the scale factor.
Here, 3 is the scale factor.
Hence, (x,y)(3x, 3y) shows dilation
