Step-by-step explanation: because when you're doing absolute value you're trying to find the opposite of the opposite so then -9 will be positive which 9 and -4 will be positive which is 4 but when you're trying to figure out which positive number is greater you have to think about which positive number is farthest from 0 which give you your answer |-9| or just 9 because |-9| is now positive since you did absolute value and 9 is farthest from 0 than 4.
