A triangle with vertices at A(20, -30), B(10, -15), and C(5,-20) has been dilated with a center of dilation at the origin. The image of B, point B', has the coordinates (2, -3). What is the scale factor of the dilation?

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
