Question

Given are the coordinates for triangle MNP. Enter the coordinates for this dilation.

M(2, 2), N(-1, 1), P(0, -1), DO,3

M' = ( , )
N' = ( , )
P' = ( , )

Answer 1

M' = ( 6,6 )
N' = (-3,3, )
P' = (0,-3 )

So the cale factor is 3 with center of dilation at

the origin.


A dilation of scalar factor k whose center of

dilation is the origin
may be written: Dk (x, y) = (kx, ky).
