Reading a number line from left to right, what happens to the values?
AThey get steadily smaller
BThey stay exactly the same
CThey rise then fall again
DThey get steadily larger
Answer & Solution
Correct answer: D. They get steadily larger
1. Negative numbers are less than zero and sit to the left of it.
2. Positive numbers are greater than zero and sit to the right of it.
3. So moving rightward along the line always means moving to larger values.
4. This is what lets a number line be used to compare any two integers.
