To find the image vertices after a dilation with center (0,0) and a scale factor of 4, we can multiply the coordinates of each vertex by the scale factor.
Point A:
x-coordinate of A after dilation = -3 * 4 = -12
y-coordinate of A after dilation = 1 * 4 = 4
Therefore, the image vertex of A is (-12, 4).
Point B:
x-coordinate of B after dilation = 4 * 4 = 16
y-coordinate of B after dilation = -3 * 4 = -12
Therefore, the image vertex of B is (16, -12).
Point C:
x-coordinate of C after dilation = 2 * 4 = 8
y-coordinate of C after dilation = 3 * 4 = 12
Therefore, the image vertex of C is (8, 12).
Point D:
x-coordinate of D after dilation = -1 * 4 = -4
y-coordinate of D after dilation = 4 * 4 = 16
Therefore, the image vertex of D is (-4, 16).
So, the image vertices for the given quadrilateral after the dilation are (-12, 4), (16, -12), (8, 12), and (-4, 16).
