Question

a mountain climber reached an elevation of 1,600 feet above sea level. which number line represents all locations below the climbers elevation?

Explanation:

Step1: Analyze the problem

We need to represent all elevations below 1600 feet on a number - line. On a number - line, numbers less than a given number \(a\) are to the left of \(a\).

Step2: Check the number - line representations

• For a number \(x\) representing the elevation, if \(x<1600\), the arrow should point to the left.
• The point at 1600 should be a hollow circle (since we are looking for values strictly less than 1600, not including 1600 itself)

Answer:

The fourth number - line (the one with a hollow circle at 1600 and the arrow pointing to the left) represents all locations below the climber's elevation.
