The dashed triangle is the image of the solid triangle. The center of dilation is (−4,−4). What is the scale factor used to create the dilation?
Looking at the figure and its image, three things are immediately obvious.....
The image is bigger
The image is inverted.
The figure and the image have a common point.
The common point is the centre of dilation.
The fact that it lies BETWEEN the image and the figure means that the SF is a negative number.
This accounts for the fact that the image is inverted.
To find the Scale Factor divide
Looking at the horizontal lines we see..
