What symbol represents a constant in the equation for inverse variation?

In the context of inverse variation, a constant is typically represented by the letter "k." In an inverse variation relationship between two variables, say x and y, the equation is expressed as y = k/x, where k represents the constant of variation. This means that as one variable increases, the other decreases in such a way that their product remains constant at k.

This choice indicates that k acts as the multiplier that captures the relationship between the two variables in inverse variation. The concept of inverse variation is vital in understanding how quantities interact when one increases and the other necessarily decreases, while still reflecting a fixed relationship described by the constant k.
