Question

Triangle ABC has vertices at (–1, 3), (2, 1), and (–2, –1). Using triangle ABC as the pre-image and the origin as the center of dilation, which of the following is not a coordinate of a dilation that uses a scale factor of 4?

Answer 1

rule for `dilation` by a scale factor of \(\color{red}{k}\) :

\((x, y) \to (\color{red}{k}x, \color{red}{k}y)\)

Answer 2

Apply that to each of the given vertices and see what u get
