Here's a "mathematical" way to compute the coordinates of the new point from the old point

 

New x coordinate  =  [ ( old x coordinate - dilation x coordinate] (scale factor + dilation x coordinate

 

New y coordinate  =  [ ( old y coordinate - dilation y coordinate] (scale factor + dilation y coordinate

 

So...for  (-4, - 2)  we have

 

New x coordinate  = [ (-4 - - 2) ] (2) + (-2)   -  [-2](2) + (-2)  =  -4 - 2  =  (-6)

 

New y coordinate  =  [ (-2 - - 2) ] (2)  + (-2)  = [ 0](2) + (-2)  = (-2)

 

So  (-4, -2)  translates to (-6, - 2)

 

I'll let you figure the other three points from the old ones

 

 

cool cool cool
