The rule for the dilation of quadrilateral qrst to the image q'r's't' is do,0.5(x, y) → (0.5x, 0.5y). what are the coordinates of q', if q(0, 2)?

Applying the rule for dilation, we will multiply the scale factor to its coordinates. Having Q (0,2) and DO 0.5(x.y), the coordinates of Q' will be:
x = (.5)(0) = 0y = (.5)(2) = 1
Therefore coordinates of Q' is (0,1) 
*Having a scale factor of >1, the figure is said to be reduced.

I’ll you if you answer my questions!
