Let's begin by listing out the given information:
Direct variation refers to the relationship between two variables such that one variable is equivalent to the product of a constant & the other variable. Such that, an increase in one variable produces a commensurate increase in the second variable & a decrease in one variable produces a commensurate decrease in the other variable
Mathematically,
Indirect variation refers to a relationship between two variables such that an increase in one variable produces a decrease in the second variable & a decrease in one variable produces a commensurate decrease in the other variable
Mathematically,
Looking at the picture, we will observe that:
Situation 1 is a direct variation (the more people sign up with the local league, the more money is generated)
Situation 2 is an indirect variation (the more money a student raises. the lesser the loan to take out)
Situation 2 is inverse variation because M = 50,000/L
