    A(-3, 4) B(3, 1) C(-1, -5) Borrowing from the definition of Mathematical Dilation "Dilations. A dilation is a transformation (notation ) that produces an image that is the same shape as the original, but is a different size. A dilation stretches or shrinks the original figure. The description of a dilation includes the scale factor (or ratio) and the center of the dilation.." Source: http://regentsprep.org/regents/math/geometry/gt3/Ldilate2.htm The equation for dilating is (x, y) = (kx, ky), thus A(-3 * 2, 4 * 2) B(3* 2, 1 * 2) C(-1 * 2, -5 * 2) Notice, we are multiplying everything by 2. (Dilation involves multiplying!) Solve to get your answer.

    A'(-6,8) B'(6,2) and C'(-1,-10) The last part. (-1, -5) = (-1 * 2, -5 * 2)...... -1 * 2 = -2..... = (-2, -10)
