Answer:


(-(3)/(2),-1)

Explanation:

From the graph in the attachment Y has coordinates:Y(3,2)

The transformation rule for a dilation with a scale factor k about the origin is:


(x,y)\to (kx,ky)

In this case we have
k=-(1)/(2)

We substitute the coordinates and
k=-(1)/(2) to get:


Y(3,2)\to Y'(-(1)/(2)*3,-(1)/(2)*2)

This simplifies to:


Y(3,2)\to Y'(-(3)/(2),-1)

The first choice is correct.
