The image point of A after a translation right 1 unit and down 2 units is the point B (9,3). Determine the coordinates of the pre-image point A.

Alright, it went 1 to the right and down 2 times.
So for point B, you calculate the opposite.
Point B goes 1 left while going up by 2.
(9 - 1, 3 + 2) = (8, 5)
Pre-image point A is (8, 5)
Answer:
(8,5)
Step-by-step explanation:
A(x,y). (X+1,y-2) =B (9,3)
The coordinates of a are (8,5)
