B. Yes, Every 3 days, sales increase by $1000
Step-by-step explanation:
A proportional relationship exists because the line cuts across the point of origin, (0, 0).
Constant rate of change is that there is an equal sales increase of $1,000 on every 3 days. Thus, on day 3, sales was $1,000. On day 6, sales was $2,000.
This shows proportional increase of $1,000 of sales, every 3 days.
The slopes of both lines are equal so they're parallel.
