Key Concepts:
- Understanding Linear Equations – The general form of a linear equation is (y = mx + b), where (m) is the slope and (b) is the y-intercept.
- Identifying Slope and Intercept – The slope represents the rate of change, while the y-intercept shows where the line crosses the y-axis.
- Choosing the Best Linear Model – A model that closely follows data points is the best representation.
- Line of Best Fit – A straight line that best represents data points on a scatterplot.
Skills Covered:
- Identify the most appropriate linear equation for a scatterplot.
- Choose the equation that best represents a given line of best fit.
- Determine how many data points fall above or below a given line of best fit.
