Scale Factor Dilation

A triangle has the following vertices: A(-1,1) B(6,-2) C(3,5). If the triangle undergoes a dilation with a scale factor of 4, what will be the coordinates of C'?

• A' (5,5) B'(23, -2) C'(15, 23)

• A' (-5,5) B'(-23, -2) C'(16, 23)

• A' (-4,4) B'(24, -2) C'(15, 23)

• A' (-4,4) B'(24, -8) C'(12, 20)

Jashon performed a transformation on a triangle with pre-image coordinates D(-6,0) E(-6,3) and F(-9,9). The coordinates of the image are D'(-2,0) E'(-2,1) and F' (-3,3). He challenges his friend Steve to describe the transformation. What response is correct?

• The pre-image was translated 3 units to the left

• The pre-image was translated 3 units to the right

• The pre-image was dilated by a scale factor of 1/3.

• The pre-image was dilated by a scale factor of 3.
