Question

A dilation maps (8, 12) to (2, 3). What are the coordinates of the image of (9, 3) under

the same dilation?

Answer 1

(9/4,3/4) or (2.25, 0.75)

Explanation:

The dilation is 1/4. We can tell this by looking at (8,12) and (2,3). 8*1/4=2 and 12*1/4=3. So therefore we just need to times 9 and 3 by 1/4. 9*1/4=2.25 or 9/4 and 3*1/4=0.75 or 3/4. so the dilation (9/4, 3/4). I believe this is correct but if I am not please tell me.
