Exercise 23 Page 560

To obtain the image of a vertex after a dilation with scale factor $k,$ multiply its coordinates by $k .$

Graph:

Coordinates: $A^{'} (- 9, 3),$ $B^{'} (0, 6),$ $C^{'} (6, - 6)$

Practice makes perfect

Let's mark the given coordinates and graph the figure.

To find the coordinates of the image after a dilation with a scale factor of

k,

we multiply each coordinate of the preimage by

k .
