A triangle has vertices with coordinates A(2,0), B(3, -1) and C(-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 new image?
A'(5,3), B'(6,2), C'(1,-2)
A'(6,0), B'(9,-3), C'(-6,-15)
A'(2/3,0), B'(1,-1/3), C'(-2/3,-5/3)
A'(-1,-3), B'(0,-4), C'(-5,-8)

bigger
Which of the following algebraic rules represents an enlargement? Select all that apply.
(x, y) --> (3x, 3y)
(x, y) --> (0.5x, 0.5y)
(x, y) --> (0.75x, 0.75y)
(x, y) --> (0.999x, 0.999y)
(x, y) --> (5x, 5y)
Point A is ( 7, 3) and Point A' is ( 21, 9). What is the algebraic rule for this dilation if the center of dilation is at the origin?
f(x,y) →(31x, 31y)
f(x,y)→(3x, 3y)
f(x,y) →(x+14, y+6)
f(x,y) → (0x, 0y)
