Answer:
(-3.2 , 12.3) 
(0.7 , 3.6) 
Explanation:
The rule : 
 
(x, y)→(x−7.5, y+6.8) 
 
For the x - coordinate ; Subtract 7.5 
For the y - coordinate `; add 6.8 
First input : (4.3, 5.5) 
 
Output : 
x = 4.3 - 7.5 = - 3.2 
y = 5.5 + 6.8 = 12.3 
Output = (4.3, 5.5) →(-3.2 , 12.3) 
Second input : (8.2, -3.2) 
 
Output : 
x = 8.2 - 7.5 = 0.7 
y = - 3.2 + 6.8 = 3.6 
Output = (8.2, -3.2)→(0.7 , 3.6) 
The outputs obtained are : 
 
(-3.2 , 12.3) and (0.7 , 3.6)
