Question

The vertices of triangle R'S'T' are R'(1, 3), S'(6, 4), and T'(4, 2). If triangle RST was dilated about the origin with a scale factor of 3, what are the coordinates of its vertices?

A.
R(–3, –1), S(–4, –6), T(–2, –4)
B.
R(2004-01-04-05-00_files/i0320002.jpg, 1), S(2, 2004-01-04-05-00_files/i0320003.jpg), T(2004-01-04-05-00_files/i0320004.jpg, 2004-01-04-05-00_files/i0320005.jpg)
C.
R(1, –3), S(6, –4), T(4, –2)
