The scale factor used to create the image is 2.
This can be determined by looking at how the x and y coordinates of each vertex have changed. For example, the x-coordinate of point A has changed from -13 to -32.5, which is a change of 19.5. Similarly, the y-coordinate of point A has changed from -4 to -10, which is a change of 6.
Since both changes are multiplied by the same number, the scale factor is 2.
Triangle ABC is dilated about the origin to create triangle A′B′C′.
Triangle ABC with vertices at A negative 13 comma negative 4, B negative 6 comma negative 4, and C negative 6 comma 4 and triangle A prime B prime C prime with vertices at A prime negative 32.5 comma negative 10, B prime negative 15 comma negative 10, and C prime negative 15 comma 10.
