(-6,-4)
If you dilate a point, (c,d) about (a,b) by a scale factor by k. You'll going to subtract each coordinates where the point will be dilated about (a,b) from the point (c,d) and then multiply them by k. This would be the formula if you want: (k(c -a), k(b -d))
Let's say F is the dilation of D about the origin or (0,0) then the x coordinate of F would be
This would be the y coordinate of F:
Thus the coordinates of F is (-6,-4)
The given expression is
This can be simplified as :
=
We know that:
Similarly we also can simplify:
So our expression will look like this:
=
=
=
=
This can also be written as:
So the Answer is Option B
