Question Analysis

The main focus is to determine whether the dilation is an enlargement or a reduction and find the scale factor, given the coordinates of point  and its image  with the origin as the center of dilation.

Key Concept Explanation

For a dilation centered at the origin, if the scale factor k > 1, it is an enlargement; if 0 < k < 1, it is a reduction. The scale factor  can be calculated using the formula  for a point  and its image
