When the point (-3,7) is dilated with the center of dilation at the origin, then the image of
the point is (-12.75, 29.75).

What is the scale factor of this dilation?

1) 4
2) 4.25
3) 9.75
4) 10

Respuesta :

Answer:

4.25

Step-by-step explanation:

To find the scale factor divide the image coordinates by the original coordinates, that is

scale factor = [tex]\frac{-12.75}{-3}[/tex] = [tex]\frac{29.75}{7}[/tex] = 4.25

The answer would be 4.25
