(1) E = (0,0) F(1,5) G(7,2) center of dilation = (5,2) scale factor = 2
Dilation rule is
Reverse the signs on the coordinates of the center = ( -5 , -2)
The "new " coordinates are ( x - 5, y - 2)
Apply the scale factor = (2x - 10, 2y - 4)
Add back the center coordinates = ( 5, 2)
[ (2x - 10 + 5). ( 2y - 4 + 2) ] =
( 2x - 5 , 2y - 2)
E' = [ (2(0) - 5, 2(0)-2) ] = (-5, -2 )
F' = [ ( 2(1) - 5 , 2(5) -2) ] = ( -3, 8)
G' = [ 2(7) - 5, 2(2) - 2 ] = ( 9, 2)
