Describe the similarity transformation that maps $$\Delta ABC$$ to $$\Delta DEF$$ (dilations have a center at the origin).

translation 4 units right and 3 units down followed by a dilation with a scale factor of 2

dilation with a scale factor of 2 followed by a translation 4 units right and 3 units down

dilation with a scale factor of $$\frac{1}{2}$$ followed by a translation 4 units left and 3 units up

translation 4 units left and 3 units up followed by a dilation with a scale factor of $$\frac{1}{2}$$

$$\Delta ABC$$ has vertices at A(-9, 0), B(0, 8) and C(-4, -10) Match the scale factor with the coordinates of its image after a dilation centered at (0, 0) scale factor of 1.5
