Question

Rectangle ABCD
is drawn on a coordinate plane. If the rectangle were dilated using a magnitude of 3
and center of dilation at (3,0)
, what would be the corresponding ordered pair to point A
?

(1 point)

Answer 1

I don't see the coordinates of A in your message. With a center of dilation C = (3,0) and scale factor k = 3, the image A' of a point A = (x,y) is

A' = C + k(A − C) = (3 + 3(x − 3), 0 + 3(y − 0)) = (3x − 6, 3y).

If you tell me A's coordinates I can give the numeric ordered pair. (Example: if A = (5,4) then A' = (3·5 − 6, 3·4) = (9,12).)
