answer: option a.
1. dilation is defined as a transformation in which the figure is enlarged or reduced.
2. for dilation you have:
- a scale factor, that determines how much the figure will be reduced or enlarged.
- the center of dilation, which is defined a a fixed point in the plane.
3. if the figure is dilated with a scale factor of 4 and the center of dilation at the origin, you must multiply the coordinates of the original figure bu 4. then:
