The rectangle is the image after a dilation with the center of dilation at the origin of rectangle ABCD. The pre-image of A prime, point A, has coordinates of (–4, 3.2). What is the scale factor of the dilation and what are the coordinates of point C? On a coordinate plane, rectangle A prime B prime C prime D prime has points (negative 10, 8), (negative 6, 8), (negative 6, negative 2), (negative 10, negative 2). Point A is at (negative 4, 3.2).
