9. A triangle has vertices A(2, 3.5), B(0, 6), and C(–2, 3). After dilation the coordinates of the triangle are A'(8, 14), B'(0, 24), and C'(–8, 12). What is the algebraic representation for the dilation?

• (x, y) --> (2x, 2y)

• (x, y) --> (3x, 3y)

• (x, y) --> (4x, 4y)

• (x, y) --> (x, y)

10. Triangle ABC has vertices A(1, 4), B( 1, 5), and C(1, 4). The triangle is dilated with a scale factor of 5, and the dilation will be centered at the origin. Write an algebraic representation for the dilation. Determine the coordinates of the image of point C after the dilation.

• (x, y) --> (5x, 5y); A’(5, -20)

• (x, y) --> (5x, 5y); A’(0, 5)

• (x, y) --> (5x, 5y); A’(5, 20)

• (x, y) --> (5x, 5y); A’(0, -5)
