Question

If a figure is dilated by a scale factor of 3, what were the coordinates of the pre-image of W'(-6, 9)?

W(-18, 27)
W(-3, 12)
W(-2, 3)
W(-9, 6)

Answer 1

We are given scale factor k=3. This means that each coordinate of a point is multiplied by 3 to get final point.

W' = 3*W

We can use this to find original point.

-6 = 3x
x = -2

9 = 3y
y = 3

So we have 
W(-2,3)

Answer 2

Answer:

The correct answer is: C

Step-by-step explanation:

W(-2, 3)
