Answer
Explanation:
Step1: Observe the scatter - plot trend
As the age of the laptop increases, the price decreases.
Step2: Estimate for a 4 - year - old laptop
Locate age = 4 on the x - axis. Looking at the trend of the data points, we can estimate the price. The data points seem to follow a rough linear trend. By visual inspection, for an age of 4 years, the price is around $300 - $400. Let's say around $350.
Step3: Estimate the age for a $200 laptop
Locate price = 200 on the y - axis. By following the trend of the data points, we can estimate the age. The age corresponding to a price of $200 is around 7 years.
Answer:
- $350
- 7 years
