Adilation maps (4, 6) to (2, 3). under the same dilation, (-1,3) would be mapped to

(-1/2,3/2)

Step-by-step explanation:

The rule for dilation about (0,0) by a scale factor is given as:

(x,y)(kx,ky)

So if (4,6) was mapped to (2,3) by dilation it means;

x=4

kx=2

k=2/4 =1/2

Hence in this case, the dilation rule is ;

(x,y)(1/2x ,1/2y)

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

                         (-1/2, 3/2)

nope.   happens to me as well.
