How do you create a residual plot with a linear regression equation and data?

To create a residual plot with a linear regression equation and data, first fit a linear regression model to your data to obtain the predicted values. Then, calculate the residuals by subtracting the predicted values from the actual values. Plot the residuals on the y-axis against the predicted values (or the independent variable) on the x-axis. This plot helps to visualize the distribution of residuals and check for patterns that may indicate violations of regression assumptions.
