a) A = (5, 1), b) A = (1,11)

Step-by-step explanation:

given A is (2,3), question a is represented by a shift of this point 3 units to the right, and 2 units down which means (x,y) → (x +3, y - 2) or T(3,-2)(x,y). (2,3) → (x + 3, y - 2) = (2 + 3, 3 - 2) = (5, 1).

Question b represents a shift of this point one unit to left, and 8 units up which is represented by (x,y) → (x -1 , y + 8) or T(-1,8)(x,y).

(2,3) → (x - 1, y + 8) = (2 - 1 , 3 + 8) = (1, 11).
