Question

Dilate the figure by a scale factor of 3 with the origin as the center of dilation. Write the coordinates of the image. 
A(3, 3), B(6, 6), C(9, 3)

  1. A'(9, 9), B'(18, 18), C'(27, 9)
  2. A'(6, 6), B'(9, 9), C'(12, 6)
  3. A'(0, 0), B'(3, 3), C'(6, 0)
  4. A'(1, 1), B'(2, 2), C'(3, 1)

Hint:

Writing the image of the given coordinates after dilating the figure by a scale factor

The correct answer is: A'(9, 9), B'(18, 18), C'(27, 9)


    A(3, 3), B(6, 6), C(9, 3)
    Dilate the figure by a scale factor of 3 with the origin as the center of dilation.
    coordinates of the image are Aˈ(3x3, 3x3) Bˈ(6X3, 6X3), Cˈ(9X3, 3X3)
    A'(9, 9), B'(18, 18), C'(27, 9)
