Find the coordinate of the image of the point (4, 2) dilated with center at the origin, scale factor 1/2 .

(-4, 2) is the first image of the point. Dilating the result involves taking the distance from the origin, which is $\sqrt{20}$, and multiplying that against (-4, 2), which results in (-4*sqrt(20), 2*sqrt(20))

i love to eat momo..its my favourate

4. momo

my options don't have square roots in them (8,4) (-4, 2) (2, 1) (2, 4)

5. anonymous

oh scale factor 1/2... it would be (2, 1)
