Polygon WXYZ has vertices W(−2,−1) , X(−2,3) , Y(0,4) , and Z(0,0) . After a dilation the vertices of the image are W'(−4,−2) , X'(−4,6) , Y'(0,8) , and Z'(0,0) . Determine the scale factor of the dilation.

Answer:

scale factor (k) is 2

Step-by-step explanation:

Look at W and W'. W is (-2, -1), but W' says (-4, -2). 2 x 2 is 4 and 1 x 2 is 2. Both coordinates were multiplied by 2. The same goes for all the other vertices, so it would be k = 2.
