To solve the problem, we need to determine when the number of students in Broward County first exceeded 1010 thousand, based on the scatterplot and its trendline.

From the scatterplot:

1. The y-axis represents the number of students (in thousands), and the x-axis represents the year.
2. The trendline steadily increases over time, with markers at intervals between 1960 and 1992.
3. The value of 1010 thousand students is close to the top of the y-axis (1020 thousand).

**Approximating from the graph:**
- By following the trendline and extending it visually, the number of students reaches or exceeds 1010 thousand around **1991**. 

Thus, the correct answer is **(D) 1991**.

1. How can we derive an equation for the trendline to predict values more accurately?
2. What other ways can we estimate values beyond the plotted data points?
3. How could we determine the rate of student growth based on the trendline?
4. In what ways could outliers in the data affect the trendline's accuracy?
5. How would this scatterplot analysis change if we had yearly data points instead of intervals?

**Tip:** When working with scatterplots, always check if there's a trendline or pattern in the data points to make accurate predictions.

According to the trendline in the scatterplot above, which of the following best approximates the year in which the number of students in Broward County first exceeded 1010 thousand?
