Question

5. Under a dilation of scale factor 3with the center at the origin, if R(4,5),what will be the coordinates of thePoint R'?

Answer 1

To find the coordinates of R', multiply each coordinate by 3.

`R(4,5)\to R^(\prime)(4\cdot3,5\cdot3)\to R\text{'}(12,15)`

Therefore, the coordinates of point R' are (12,15).
