Question

a drilling crew drills the same depth each day for 7 days. at the end of the 7 days, the crew has dug to a depth of 1344 feet. the number zero represents ground level. select the number line that represents the drilling depth relative to ground level. there are two number line options: the first has a blue dot at -1344 and 0 with one dashed arrow from 0 to -1344; the second has a blue dot at -1344 and 0 with seven dashed arrows from 0 to -1344 (indicating 7 days of drilling).

Explanation:

Step1: Analyze Drilling Direction

Drilling depth is below ground level (0), so it's negative. The crew drills the same depth each day for 7 days, so there should be 7 equal - length arrows (representing daily drilling) from 0 moving left (negative direction) to - 1344.

Step2: Compare Number Lines

The first number line has 1 arrow from 0 to - 1344, which doesn't represent 7 days of drilling. The second number line has 7 arrows (one for each day) from 0 moving left to - 1344, which matches the 7 - day drilling process.

Answer:

The Middle Graph (the second number line with 7 dashed arrows from 0 to - 1344)
