Question

(80 POINTS) What rule describes a dilation with a scale factor of ½ and the center of dilation at the origin?

Answer 1

C. (x,y) → (1/2x,1/2y)

Explanation:

Dialation means to multiply each coordinate by scale factor and in this case it's 1/2

Answer 2

C

Explanation:

(x, y) -> (1/2x, 1/2y)

When you dilate a side, point, etc, you are multiplying the original dimension by the scale factor. That is represented in option C: the original x and y are multiplied by the scale factor, 1/2! Hope that helps! :)
