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
