The formula to calculate the Proportionality Constant is:
\[ k = \frac{y}{x} \]
Where:
The proportionality constant is a constant value that relates two variables that are directly proportional to each other. In the equation \( y = kx \), \( k \) is the constant of proportionality that describes how the value of one variable (y) changes when the other variable (x) changes. This constant is a fundamental concept in various fields such as physics, mathematics, and engineering.
