Question Analysis

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

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
