Answer: Choice B</h3>
D ' (-7, 7) , E ' (-3.5, 14) , F ' (7, 10.5) , G ' (-3.5, -7)
================================================
Explanation:
Point D has coordinates x = -2 and y = 2. Multiply each by the scale factor 3.5 to get
3.5*(-2) = -7
3.5*(2) = 7
Therefore the new location is now (-7, 7) which is where point D ' is at.
The same idea applies to all of the other points
E(-1, 4) ----> E ' (-3.5, 14) after multiplying both coordinates by 3.5
F(2, 3) ----> F ' (7, 10.5) doing the same to the coordinates of point F
G(-1, -2) -----> G ' (-3.5, -7) ditto to the coordinates of point G
Extra info: the preimage DEFG enlarges to the image D'E'F'G' because the scale factor 3.5 is larger than 1.
