Answer:
The scale factor of dilation is 1/2
New coordinates are: (-3, 3/2)
Step-by-step explanation:
a) A dilation maps (4,6) to (2,3)
we see that (4/2,6/2) = (2,3)
So, the scale factor of dilation is 1/2
b) if (-6,3) is under same dilation, their new coordinates will be?
We have to multiply (-6,3) by scale factor of 1/2
(-6*1/2,3*1/2) = (-3,3/2)
So, new coordinates are: (-3,3/2)
