Final answer:
The appearance of positive slope differs from negative slope and zero slope.
Step-by-step explanation:
The appearance of positive slope differs from negative slope and zero slope in the following ways:
- Positive slope: The line goes up from left to right, indicating a positive change in the dependent variable for every unit increase in the independent variable.
- Negative slope: The line goes down from left to right, indicating a negative change in the dependent variable for every unit increase in the independent variable.
- Zero slope: The line is horizontal, indicating no change in the dependent variable for every unit increase in the independent variable.
