A correlation coefficient of -1 indicates a perfect negative linear relationship between two variables. This means that as one variable increases, the other decreases in a perfectly consistent, linear manner. In a scatter plot, all data points would lie exactly on a downward-sloping line, showing an inverse relationship where one variable's increase corresponds to the exact decrease in the other variable.
