How would I approach this problem?
![The scatter plot shows the time spent studying, \( x \), and the quiz score, \( y \), for each of 24 students.
(a) Write an approximate equation of the line of best fit for the data. It doesn't have to be the exact line of best fit.
(b) Using your equation from part (a), predict the quiz score for a student who spent 50 minutes studying.
Note that you can use the graphing tools to help you approximate the line.
**Graph Description:**
- The plot has the x-axis labeled "Time spent studying (in minutes)" ranging from 0 to 100 minutes.
- The y-axis is labeled "Quiz score" ranging from 0 to 100.
- The scatter plot shows 24 blue crosses indicating different data points.
- The data points show an upward trend, indicating a positive correlation between time spent studying and quiz scores.
### Interactive Features:
- There are tools shown for drawing, erasing, and resetting the approximations.
- Specific fields are provided for entering answers to part (a) and part (b).
