The correct response to describe the dilation of triangle \( ABC \) with a scale factor of 5 and a center point of dilation at the origin (0, 0) is:
Triangle \( A'B'C' \) is 5 times as large as triangle \( ABC \) and is 5 times as far from the center point of dilation.
When a triangle is dilated from a point (in this case, the origin) with a scale factor of 5, each vertex of the triangle will move to a position that is 5 times further away from the center of dilation, resulting in a triangle that is also 5 times larger in size.
