We can use this to find the post-image vertexes

 

New Vertex   =  (  Old vertex  - Dilation Center) *Scale Factor +  Dilation Center

 

Because the Dilation Center is (0,0), this simplifies to :

 

New Vertex  =  (Old Vertex ) * Scale Factor

 

 

So  we have

 

A'  =  (-4, -1)*2  =  (-8, -2)

B'  =  (-4, -3)*2  =  (-8, -6)

C'  =  (-1, -3)*2  =  (-2, -6)

 

 

 

cool cool cool
