Question

What are the coordinates of R′ for the dilation D_(0.5, P)(PQRS)?

coordinates =(  ,  )

Answer 1

OK, we want a dilation with a scale factor of 0.5 (1/2) about point P. The question asks what are the coordinates of point R (R') after the dilation. Point R is 4 units to the right and 5 units up from point P. The scale factor of 0.5 cuts those distances in half. So R' will be 2 units to the right and 2.5 units up from point P. What coordinates does that make R' have?
