Exercises: Fitting a Linear Function to a Scatter Plot
Work through each section in order. When a scatter plot is shown, first decide whether it suggests a LINEAR association before fitting a line. To find a line's equation, read two convenient points ON the line (not necessarily data points), compute slope as rise over run, and find the y-intercept. Remember: a line of fit balances points above and below and need not pass through any data point.
