Math Problem Statement
Solution
The given equation is . To determine whether and are proportional, we need to check if their relationship is of the form , where is a constant (the constant of proportionality).
Analysis:
- The equation is not linear because it involves .
- Proportionality implies a linear relationship, but in this case, is proportional to , not directly to .
Conclusion:
- and are not directly proportional because .
- However, is proportional to , with the constant of proportionality being 1.

- What is the significance of the constant of proportionality in a proportional relationship?
- Can be transformed to show and in direct proportion under any conditions?
- How would the relationship change if there was a coefficient in front of ?
Tip:
Proportionality often involves checking if one variable is a constant multiple of the other. Always analyze the form of the equation to distinguish direct, inverse, or quadratic proportionality!
