The coordinates of the image after dilation are
A (-12 , -12) , B (6 , -3) , C (3 , 3) ⇒ answer B
Step-by-step explanation:
A dilation is a transformation that produces an image that is the
same shape as the original, but in a different size
When you dilate a figure, with
- The center of dilation is the origin
- The scale factor of dilation is k
Then the coordinates of each point of the figure is multiplied by k
to find the image of the figure after dilation
∵ ABC has coordinates of A (-8 , -8), B (4 , -2), and C (2 , 2)
∵ ABC is dilated by scale factor 1.5
∵ The center of dilation is the origin
- Multiply the coordinates of points A, B, and C by 1.5
∴ The image of point A = (-8 × 1.5 , -8 × 1.5) = (-12 , -12)
∴ The image of point B = (4 × 1.5 , -2 × 1.5) = (-6 , -3)
∴ The image of point C = (2 × 1.5 , 2 × 1.5) = (3 , 3)
The coordinates of the image after dilation are
A (-12 , -12) , B (6 , -3) , C (3 , 3)
