What is the distance between -9 and -2 on a number line

7

Step-by-step explanation:

The distance between -9 and -2 on a number line is 7. If you check the picture attached, you will find that there are 7 units between -9 and -2.

Another way to calculate this is by subtracting the two numbers (In any order) and then taking the absolute value of the number. Therefore:

-9 - (-2) = -7

Abs(-7) = 7

Also it could be:

-2 - (-9) = 7

Abs(7) = 7

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
