Interpreting Slopes and y-Intercepts of Lines of Best Fit

Students interpret slopes and y-intercepts of lines of best fit based on real-world scenarios in this eighth-grade worksheet! On a scatter plot with a linear association, the line of best fit (also called a trend line) is the line that best represents the data. In this two-page practice worksheet, students are given scatter plots with real-world data. Each scatter plot has the line of best fit given. Students are asked to write the equation of the line of best fit and interpret the slope and y-intercept in the context of each given scenario. This worksheet offers a helpful way to build students' data analysis skills and prepare them for higher level statistics courses. To learn more about lines of best fit, try the Estimating Lines of Best Fit worksheet!
