How do we graph dialations?

The way you can dodialations is to multiply the dimension of the original im age by the scale factor to get the dimension of the dialated image.

Scale Factor is when the image stretches or shrinks

If the scale factor is greater than zero and less than 1 then the image will shrink.

If the scale factor is greater than 1 then the image will stretch

Ex.)

Practice Question:

 1) Perform a Dilation of ½ on point A (2, 4).

 2) What are the points of triangle ABC where A(4,3) B(6,1) C(18,4) where it was dialated by 4
