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

R(–3, –1), S(–4, –6), T(–2, –4

R(1, –3), S(6, –4), T(4, –2)

R(3, 9), S(18, 12), T(12, 6)

R(1/3, 1) S(2, 4/3) T(4/3, 2/3)

im thinking its the 3rd one but I really just don't know please help

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


R(–3, –1), S(–4, –6), T(–2, –4 

R(1, –3), S(6, –4), T(4, –2)

R(3, 9), S(18, 12), T(12, 6)

R(1/3, 1) S(2, 4/3) T(4/3, 2/3)
