Question

rectangle GHJK has vertices G(-1, -2), H(-1, 3), J(4, 3), and K(4, -2). it is dilated by a scale factor of 3, and its origin is the center of dilation. find the corridinates of the vertices its image

Answer 1

Example:
dilation of ABC about origin, with dilation factor of 5.
A(0,0),B(2,3),C(1,6)
A'(5*0,5*0)=A'(0,0)
B'(5*2,5*3)=B'(10,15)
C'(5*1,5*6)=C'(5,30)
