A triangle has vertices with coordinates (2,0), (3, -1) and (-2,-5). If the triangle is dilated by a scale factor of 3 with the origin as the center of dilation, what are the coordinates of the vertices of the image?
a
(5,3), (6,2), (1,-2)
b
(6,0), (9,-3), (-6,-15)
c
(2/3,0), (1,-1/3), (-2/3,-5/3)
d
(-1,-3), (0,-4), (-5,-8)
