21=3x

now divide by 3 on both sides.

Maddie plots point A (1,3). She then translates
hichkok12 [17]

Coordinates of the final image is (-3,6)

Point A is (1,3)

Now applying rule(x-2,y-1)

  (1-2,3-1)=(-1,2)

So, after applying rule We get (-1,2)

Dilates the image  centered at the origin with a scale factor of 3 means that multiply coordinate point by 3.

So, after multiplying (-1,2) by 3 . We get final image is (-3,6)
