On a real number line, what is the midpoint of –4 and 18?
On a real number line, what is the midpoint of –4 and 18?
The integer halfway between –4 and 18 is 7. The number 7 is 11 greater than –4 and 11 less than 18. Another way to determine this would be to find the average of the two numbers: (–4 + 18)/2 = 14/2 = 7.

Which number below is farthest from –3 on a number line?
Which number below is farthest from –3 on a number line?
The answer here relies on knowledge of how numbers are arranged on a number line. We are looking for the number furthest from –3. The number furthest from –3 can lie either to the left of –3 which would be negative numbers that are more negative, or further from 0 than –3. The number furthest from –3 could also lie to its right on the number line, these numbers include all negative numbers between –3 and 0,0, and all positive numbers. The number that satisifes these conditions and is the furthest from –3 on the number line is –8

On a number line, what is the distance between –6 and 7?
On a number line, what is the distance between –6 and 7?
To find distance between two points, take the second and subtract the first.
So 7–(–6) = 7 + 6 = 13
