كويز تفاعلي: Equation for a line that closely fits the data and prediction

This section covers the topic of scatter plots and lines of best fit.
Students will learn how to find the equation for a line that closely fits a data set and use it to predict values that are not present in the original data set.
The exercises include interpreting the slope and y-intercept within real-world contexts like sports participation, tip earnings, and temperature effects.
