Chapter 1, Problem 71

Use a number line to determine whether each statement is true or false. 3 > -2

Verified step by step guidance
1
Understand the inequality: The statement is comparing two numbers, 3 and -2, to see if 3 is greater than -2.
Recall the number line concept: On a number line, numbers increase in value as you move from left to right. Negative numbers are to the left of zero, and positive numbers are to the right.
Locate the numbers on the number line: Place -2 to the left of zero and 3 to the right of zero.
Compare their positions: Since 3 is to the right of -2 on the number line, it means 3 is greater than -2.
Conclude the truth value: Based on the number line, the statement 3 > -2 is true.
