PLEASE PLEASE HELP ASAP WITH EXPLANATION!! Use scalar multiplication to determine the coordinates of the dilated figure. Then graph the pre-image and the image on the same coordinate grid. Quadrilateral STUV with vertex matrix [-9 6 9 -4 6 1 -3 -6]
with scale factor 1/3.

A type of transformation that occurs when a figure is enlarged or reduced, the transformation is called a dilation . A dilation requires a center point and a scale factor . You can use scalar multiplication to perform dilations in matrices. Write the vertex matrix for Δ A B C with A ( 2, 1), B ( − 1, 3), and C ( − 3, − 2) .

my answer is$ 12

step-by-step explanation:

because 15 -2=12
