Question

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

(1, 3)
(-2, 2)
(2, 2)

Answer 1

If you're referring to the origin as the center of dilation, then any point (x,y) will turn into (x*k, y*k) where k is the dilation scale factor

Answer 2

For example, if we had the point (5,7) and you dilated it with a scale factor of 10, then it would turn into (50,70)

x*k = 5*k = 5*10 = 50
y*k = 7*k = 7*10 = 70

all we're doing is multiplying the coordinates by this scale factor.

Answer 3

so the answer would be (-2,2)

Answer 4

Yes that is correct.

Answer 5

thankyou
