Question

Find the translation rule and the scale factor of the dilation that transforms Ol to ol'.es(x, y) = (x + 7, y + 8); scale factor = 2B)(x, y) = (x + 8, y + 7); scale factor = 2EliminateC)(x, y) = (x + 7. y + 8); scale factor = 3D(x, y) — (X + 8, y + 7); scale factor = 3

Answer 1

The initial circle I have been transformed to circle I' by the following transformation factor

$\begin{gathered} x\Rightarrow\text{ x+7} \\ y\Rightarrow y+8 \\ I^{\prime}\Rightarrow3I \end{gathered}$

That is, it has been shifted to right 7 units, upward 8 units, and dilated by a factor of 3

Thus the transformation rule is

$(x,y)\Rightarrow(x+7,y+8);\text{ scale factor =3}$

Hence, the correct answer is Option C
