Answer:
(x, y) ----> (x +1, y - 9)
Step-by-step explanation:
A square on a coordinate plane is translated 9 units down and 1 unit to the right.
Let's (x, y) is coordinate plane.
Here x represents the horizontal move and y represents the vertical move.
It is translated 9 units down and 1 unit right.
(x, y) ----> (x +1, y - 9)
Translation (x, y )---> (x+1, y-9)
