laps | steps
0 | 1,875
1 | 4,300
2 | 6,725

4 | 11,675
which statement is true about the graph of the line representing debi’s data?

• debi walks 1,875 steps per lap around the mall
• one lap around the mall is equal to 2,425 steps
• one lap around the mall is equal to 4,300 steps
• debi walks 0,175 steps per lap around the mall

Explanation:

Step1: Find steps per lap

Subtract 0-lap steps from 1-lap steps:
$4300 - 1875 = 2425$

Step2: Verify with other laps

Check 2 laps: $1875 + 2\times2425 = 1875 + 4850 = 6725$, matches table.
Check 3 laps: $1875 + 3\times2425 = 1875 + 7275 = 9150$, matches table.
Check 4 laps: $1875 + 4\times2425 = 1875 + 9700 = 11575$, matches table.

Answer:

One lap around the mall is equal to 2,425 steps
