You have a dilation scale factor of 2 and a center of dilation of the origin. That means every point of the dilation will be twice as far form the origin and in the same direction as it was.
options for the first blank are (2,1) (-2,-2) (1,2) (-2,2) options for the second blank are (-2,2) (4,-2) (4,2) (-2,-2)
so you would times x and y by 2?

when you start to do a dialation what do you do first
Dilate the polygon above by a scale factor of to with the origin as the center of the dilation.
Draw a line from the origin to each vertex and extend it.

take a short find cordinates multiply by 2
short cut
Find the distance from the origin to each original vertex, and double it. Place each new point on each line drawn above. |dw:1477587233153:dw|
