(there are 4 cases)
Over the x-axis: (x,y) — (x,-y)
Over the y-axis: (x,y) — (-x,y)
Over the line y=x: (x,y) — (y,x)
Through the origin: (x,y) — (-x,-y)

What are Latkes?
During Hanukkah, latkes are a delicious staple on most dinner plates. In Hebrew, the dish is known as levivot.

What is the center of dilation?
A coordinate that defines the origin of the dilation of all the transformed figures.
