What is the scale factor of a triangle with a vertex of A (-6,4) that has been dilated with the center of dilation at the origin so the vertex of its image is a' (-24,16)?

Respuesta :

Answer:

  4

Step-by-step explanation:

When the dilation is about the origin, the scale factor is the ratio of the coordinates of the image to the original.

  A'/A = (-24/-6, 16/4) = (4, 4) . . . . scale factors are both 4 for x any y

The dilation scale factor is 4.
