determine the scale factor used in the dilation of line AB, with center point of dilation at the origin.

a) -3
b) 1/3
c) -1/3
d) 3

Without knowing the lengths of line AB and its dilated image, we cannot determine the exact scale factor used in the dilation. As a result, we cannot determine whether the scale factor is -3, 1/3, -1/3, or 3.
