The constant of proportionality is

a value that relates two quantities that are directly proportional to each other. It is represented by the symbol "k" and is calculated by dividing the two quantities.

The constant of proportionality is a value that relates the quantities in a proportionate relationship. In mathematics, it is denoted by the letter "k" or any other suitable variable. The constant of proportionality can be calculated by dividing the value of one variable by the value of the other variable in a given proportion.

For example, in the equation y = kx, where y and x are variables and k is the constant of proportionality, if the value of y is 10 when x is 2, we can determine k by dividing y by x: k = y / x = 10 / 2 = 5. Therefore, the constant of proportionality in this equation is 5.

The constant of proportionality signifies how much one variable changes in relation to the other variable. It remains constant throughout the proportion and can be used to find other values in the proportionate relationship.
