The fourth tick mark below the 0 would be -8 on the number line, and the question is asking for the opposite of that answer so it would be +8 or "a distance of 4 tick marks above 0" because it's counting by 2's (has increments of 2)

What type of question was this anyway? I've never had to deal with this sort of problem
