Question

geographers use negative numbers to represent points below sea level and positive numbers to represent points above sea level. for example, the lowest point in new orleans is at \\(-2\\) meters, and the highest point is at \\(6\\) meters.

what does \\(0\\) meters represent?

choose 1 answer:
(a) the highest point in new orleans
(b) sea level
(c) the lowest point in new orleans

🆕 New Concept Discovered: Interpreting Negative Numbers in Real-World Contexts
Using zero as a reference point

Step 1: Identify the reference point

The problem states that:

• Negative numbers represent points below sea level.
• Positive numbers represent points above sea level.

The number \( 0 \) is the boundary between positive and negative numbers. Therefore, \( 0 \) meters represents the baseline reference point from which these heights are measured.

Step 2: Match with the options

Since positive is above sea level and negative is below sea level, the neutral value of \( 0 \) must represent exactly at sea level.

• A: The highest point in New Orleans is represented by \( 6 \) meters.
• B: Sea level is represented by \( 0 \) meters.
• C: The lowest point in New Orleans is represented by \( -2 \) meters.

Answer:

B Sea level
