What are the points of an image A(-3,-2) B(-3,1) C(0,3) and D(2,-1), after a dilation and a scale factor of 2?

Answer: In a dilation with scale factor k, each point (x,y) is transformed to the point (kx,ky). So, if the scale factor is 2, the points A, B, C, and D will be transformed to the following:

A' (-3 * 2, -2 * 2) = (-6, -4)

B' (-3 * 2, 1 * 2) = (-6, 2)

C' (0 * 2, 3 * 2) = (0, 6)

D' (2 * 2, -1 * 2) = (4, -2)

So, the image points after the dilation with scale factor 2 are A' = (-6,-4), B' = (-6,2), C' = (0,6), and D' = (4,-2).
