Question

What are the coordinates of the image of ΔABC after a dilation with center (0, 0) and a scale factor of 1/2? Drag numbers to complete the coordinates. Numbers may be used once, more than once, or not at all.

A: (20,2) B: (6,4) C: (6,2)

Answer 1

A because I know it’s right

Answer 2

let k denote scale factor.

we have the formula p(x,y) =P'(kx,ky) when dilated under origin with scale factor k.
