How do we graph dilations?

Aim:How do we graph dilations?


Dilations:A type of transformation that causes an image to stretch or shrink in proportion to its original size.

Scale factor: the ratio by which the image stratches or shrinks is known as the scale factor.

- Multiply the dimensions of the original image by the scale factor to get the dimensions of the dilated image.

Ex: Find the image of (3,-2) under the dilation2
               3x2=6       -2x2=-4
                       (6,-4)
