Question
The dilation D: (x, y) → (0.2x, 0.2y) has been applied to the polygon S(–5, 5), T(–5, 10), U(5, 15). What are the coordinates of the image points?
a
S'(–1, 1), T'(–1, 2), U'(1, 3)
b
S'(–4.8, 5.2), T'(–4.8, 10.2), U'(5.2, 15.2)
c
S'(–5.2, 4.8), T'(–5.2, 9.8), U'(4.8,14.8)
d
S'(–3, 7), T'(–3, 12), U'(7, 17)
a
S'(–1, 1), T'(–1, 2), U'(1, 3)
b
S'(–4.8, 5.2), T'(–4.8, 10.2), U'(5.2, 15.2)
c
S'(–5.2, 4.8), T'(–5.2, 9.8), U'(4.8,14.8)
d
S'(–3, 7), T'(–3, 12), U'(7, 17)

S(-5,5) -> S'(-5*0.2,5*0.2) = (-1,1)
and so on
