To correctly identify the variables and their placements, we need to understand the relationships between them:
1. Time is the (independent/dependent) variable:
- Time is typically the independent variable because it is what we are changing to observe its effect on another variable.
- Therefore, Time is the independent variable.
2. and should be placed on the (x-axis/y-axis):
- The independent variable is usually placed on the x-axis in a graph.
- Therefore, Time should be placed on the x-axis.
3. Parking fee is the (independent/dependent) variable:
- The parking fee depends on the amount of time parked, making it the dependent variable.
- Therefore, Parking fee is the dependent variable.
4. and should be placed on the (x-axis/y-axis):
- The dependent variable is usually placed on the y-axis in a graph.
- Therefore, Parking fee should be placed on the y-axis.
Putting it all together:
- Time is the independent variable and should be placed on the x-axis.
- Parking fee is the dependent variable and should be placed on the y-axis.
