Answer:
Option (C)
Step-by-step explanation:
If a point is dilated by a scale factor of 'k' about the origin,
Rule for the dilation,
(x, y) → (kx, ky)
By this rule, if ΔABC is dilated to form image triangle as ΔA'B'C',
A(-2, -2) → A'[2×(-2), 2×(-2)]
B(-1, 2) → B'[2×(-1), 2×(2)]
C(2, 1) → C'[2×(2), 2×(1)]
Therefore, scale factor of the dilation of the dilation will be k = 2
Option (C) will be the answer.
