Question

What is the image of (-1, 1) after a dilation of 2? (1, 3) (-2, 2) (2, 2)

Answer 1

Answer: (-2,2)

Simply multiply each coordinate by 2
x = -1 ---> x = -2
y = 1 ---> y = 2

Note: this is assuming that the center of dilation is the origin (0,0)

Answer 2

Answer:

(-2, 2)

Step-by-step explanation:

2x-1= -2

2x2= 2
