Lets say in a table there is 4 points, (200,29) (310,63) (300,51) (396,20) and if you plot the points according to the trendline what would the y value be when x is equal to 100 No explanation needed just give answer

The y-value when x = 100, based on the trendline, would be approximately **12.55**. 

Would you like details or have any questions?

Here are five related questions:
1. How do we calculate the equation of the trendline from a set of points?
2. Can you explain the different types of trendlines (linear, polynomial, etc.)?
3. What would the y-value be if x = 150 using the same trendline?
4. How does the method of least squares fit a trendline to data points?
5. How accurate is a trendline at predicting values outside the range of the given data?

**Tip:** Trendlines are most reliable within the range of data points used to generate them. Extrapolating far beyond that range may reduce accuracy.

Determine the y-value when x equals 100 using linear regression trendline for the points (200,29), (310,63), (300,51), and (396,20). This problem covers core statistical concepts like linear regression and the least squares method. Suitable for high school students in Grades 10-12.
