Question

Using a number line, how do you compare: a) Two negative integers? b) Two positive integers? c) One positive and one negative integer?

Answer 1

Negative and positive integers can be compared using a number line by considering their positions relative to zero.

Step-by-step explanation:

Using a number line, you can compare negative integers, positive integers, or a positive and a negative integer by looking at their positions relative to zero.

a) Comparing Two Negative Integers:

The integer closer to zero is considered to be greater. For example, -5 is greater than -7 because it lies closer to zero on the number line.

b) Comparing Two Positive Integers:

The integer farther from zero is considered to be greater. For example, 8 is greater than 3 because it lies farther from zero on the number line.

c) Comparing One Positive and One Negative Integer:

All positive integers are greater than any negative integers. For example, 4 is greater than -2 because all positive integers are to the right of negative integers on the number line.
