Question

How can you use a number line to determine which value is greater when two or more integers are being compared?

a) Distance from zero
b) Counting tick marks
c) Adding integers
d) Subtracting integers

Answer 1

To determine which integer is greater using a number line, compare their distances from zero; the farther to the right the integer is, the greater its value.

Step-by-step explanation:

You can look at their distance from zero to compare two or more integers using a number line. The integer further to the right on the number line is greater. Here's a step-by-step explanation:

1. Place both integers on the number line.
2. Identify the position of zero on that line.
3. Check which integer is further to the right from zero. This integer has a greater value.
4. If the integers are on the same side of zero, then the one further away from zero is the greater integer. If one integer is to the right of zero and the other is to the left, the one on the right is always greater because it is positive while the one on the left is negative.

Remember that this method uses the visual representation of a number line to compare the values of the integers based on their positions relative to zero. The option 'Distance from zero' best describes how to use a number line to determine which value is greater when comparing integers.
