Answer:
scale factor = [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Given
A(4, - 2 ) → A'(1, - [tex]\frac{1}{2}[/tex] )
To determine the scale factor compare the ratio of corresponding coordinates, image to original, that is
scale factor = [tex]\frac{1}{4}[/tex] = [tex]\frac{-\frac{1}{2} }{-2}[/tex] = [tex]\frac{1}{4}[/tex]
