Answer:
Explanation:
Rule for the dilation of a point by a scale factor 'k' about the origin is,
(x, y) → (kx, ky)
By this rule,
Coordinates of the vertices of the given triangle when dilated by a scale factor of
about the origin will be,
F(-3, -9) → F'(-1, -3)
G(-3, -6) → G'(-1, -2)
H(3, -6) → H'(1, -2)
