The correct equation that represents a constant of proportionality of 15 is:
\[ y = 15x \]
In this equation, \( y \) is directly proportional to \( x \) with a constant of proportionality of 15.
The equation \( y = x + 15 \) represents a linear relationship but not a proportional one, as it includes a constant term (15) that does not depend on \( x \).
\[ y = 15x \]
In this equation, \( y \) is directly proportional to \( x \) with a constant of proportionality of 15.
The equation \( y = x + 15 \) represents a linear relationship but not a proportional one, as it includes a constant term (15) that does not depend on \( x \).
